Previous studies have mostly focused on evaluating the safety of evacuation and the risk of fire in particular buildings. However, studies on effects of various parameters on evacuation have not been nearly done. Therefore, this paper aims at observing evacuation time under the effect of fire initiated location. In this study, evacuation simulations are performed on a 5-floor building located in Seoul, South Korea using the commercial program, Fire Dynamics Simulator with Evacuation (FDS+EVAC). Only the fourth and fifth floors are modeled with an assumption that fire starts in a room located on the fourth floor. The parameter for evacuation simulations is location of fire initiation to observe the evacuation time and safety. Results show that the location of fire initiation is closer to exit, the more time is taken to evacuate. The case having the nearest location of fire initiation to exit has the lowest ratio of successful occupants to the total occupants. In addition, for safety evaluation, the evacuation time calculated from computer simulation model is compared with the tolerable evacuation time according to code in Japan. As a result, all cases are completed within the tolerable evacuation time. This study allows predicting evacuation time under various conditions of fire and can be used to evaluate evacuation appropriateness and fire safety of building. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20simulation" title="fire simulation">fire simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=evacuation%20simulation" title=" evacuation simulation"> evacuation simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=evacuation%20safety" title=" evacuation safety"> evacuation safety</a> </p> <a href="https://publications.waset.org/abstracts/36360/a-study-for-the-effect-of-fire-initiated-location-on-evacuation-success-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36360.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5449</span> Analysis of The Effect about Different Automatic Sprinkler System Extinguishing The Scooter Fire in Underground Parking Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Hsiu%20%20Li">Yu-Hsiu Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Hsun%20%20Chen"> Chun-Hsun Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of automatic sprinkler system protects the scooter in underground parking space, the current of general buildings is mainly equipped with foam fire-extinguishing equipment in Taiwan, the automatic sprinkling system has economic and environmental benefits, even high stability, China and the United States allow the parking space to set the automatic sprinkler system under certain conditions. The literature about scooter full-scale fire indicates that the average fire growth coefficient is 0.19 KW/sec2, it represents the scooter fire is classified as ultra-fast time square fire growth model, automatic sprinkler system can suppress the flame height and prevent extending burning. According to the computer simulation (FDS) literature, no matter computer simulation or full-scale experiments, the active order and trend about sprinkler heads are the same. This study uses the computer simulation program (FDS), the simulation scenario designed includes using a different system (enclosed wet type and open type), and different configurations. The simulation result demonstrates that the open type requires less time to extinguish the fire than the enclosed wet type if the horizontal distance between the sprinkler and the scooter ignition source is short, the sprinkler can act quickly, the heat release rate of fire can be suppressed in advance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20sprinkler%20system" title="automatic sprinkler system">automatic sprinkler system</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20parking%20Spac" title=" underground parking Spac"> underground parking Spac</a>, <a href="https://publications.waset.org/abstracts/search?q=FDS" title=" FDS"> FDS</a>, <a href="https://publications.waset.org/abstracts/search?q=scooter%20fire%20extinguishing" title=" scooter fire extinguishing"> scooter fire extinguishing</a> </p> <a href="https://publications.waset.org/abstracts/120646/analysis-of-the-effect-about-different-automatic-sprinkler-system-extinguishing-the-scooter-fire-in-underground-parking-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120646.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5448</span> Utilizing Minecraft Java Edition for the Application of Fire Disaster Procedures to Establish Fire Disaster Readiness for Grade 12 STEM students of DLSU-IS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aravella%20Flores">Aravella Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Rafael%20E.%20Sotelo"> Jose Rafael E.

This platform is suitable because fire DRRR is challenging to learn in a practical setting as well as questionable with regard to supplementing the successful implementation of textbook knowledge into actual practice. The purpose of this study is to acknowledge whether Minecraft can be a suitable environment to familiarize oneself to fire DRRR. The objectives are achieved through utilizing Minecraft in simulating fire scenarios which allows the participants to freely act upon and practice fire DRRR. The experiment was divided into the grounding and validation phase, where researchers observed the performance of the participants in the simulation. A pre-simulation and post-simulation survey was given to acknowledge the change in participants’ perception of being able to utilize fire DRRR procedures and their vulnerabilities. The paired t-test was utilized, showing significant differences in the pre-simulation and post-simulation survey scores, thus, insinuating improved judgment of DRRR, lessening their vulnerabilities in the possibility of encountering a fire hazard. This research poses a model for future research which can gather more participants and dwell on more complex codes outside just command blocks and into the code lines of Minecraft itself. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=minecraft" title="minecraft">minecraft</a>, <a href="https://publications.waset.org/abstracts/search?q=DRRR" title=" DRRR"> DRRR</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/148659/utilizing-minecraft-java-edition-for-the-application-of-fire-disaster-procedures-to-establish-fire-disaster-readiness-for-grade-12-stem-students-of-dlsu-is" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148659.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5447</span> Design an Intelligent Fire Detection System Based on Neural Network and Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Majid%20Arvan">Majid Arvan</a>, <a href="https://publications.waset.org/abstracts/search?q=Peyman%20Beygi"> Peyman Beygi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sina%20Rokhsati"> Sina Rokhsati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In-time detection of fire in buildings is of great importance. Employing intelligent methods in data processing in fire detection systems leads to a significant reduction of fire damage at lowest cost. In this paper, the raw data obtained from the fire detection sensor networks in buildings is processed by using intelligent methods based on neural networks and the likelihood of fire happening is predicted. In order to enhance the quality of system, the noise in the sensor data is reduced by analyzing wavelets and applying SVD technique. Meanwhile, the proposed neural network is trained using particle swarm optimization (PSO). In the simulation work, the data is collected from sensor network inside the room and applied to the proposed network. Then the outputs are compared with conventional MLP network. The simulation results represent the superiority of the proposed method over the conventional one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intelligent%20fire%20detection" title="intelligent fire detection">intelligent fire detection</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20sensor%20network" title=" fire sensor network"> fire sensor network</a> </p> <a href="https://publications.waset.org/abstracts/55735/design-an-intelligent-fire-detection-system-based-on-neural-network-and-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55735.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5446</span> Coarse Grid Computational Fluid Dynamics Fire Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wolfram%20Jahn">Wolfram Jahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Manuel%20Munita"> Jose Manuel Munita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While computational fluid dynamics (CFD) simulations of fire scenarios are commonly used in the design of buildings, less attention has been given to the use of CFD simulations as an operational tool for the fire services. The reason of this lack of attention lies mainly in the fact that CFD simulations typically take large periods of time to complete, and their results would thus not be available in time to be of use during an emergency. Firefighters often face uncertain conditions when entering a building to attack a fire. They would greatly benefit from a technology based on predictive fire simulations, able to assist their decision-making process. The principal constraint to faster CFD simulations is the fine grid necessary to solve accurately the physical processes that govern a fire. This paper explores the possibility of overcoming this constraint and using coarse grid CFD simulations for fire scenarios, and proposes a methodology to use the simulation results in a meaningful way that can be used by the fire fighters during an emergency. Data from real scale compartment fire tests were used to compare CFD fire models with different grid arrangements, and empirical correlations were obtained to interpolate data points into the grids. The results show that the strongly predominant effect of the heat release rate of the fire on the fluid dynamics allows for the use of coarse grids with relatively low overall impact of simulation results. Simulations with an acceptable level of accuracy could be run in real time, thus making them useful as a forecasting tool for emergency response purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20simulations" title=" fire simulations"> fire simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response" title=" emergency response"> emergency response</a>, <a href="https://publications.waset.org/abstracts/search?q=forecast" title=" forecast"> forecast</a> </p> <a href="https://publications.waset.org/abstracts/50382/coarse-grid-computational-fluid-dynamics-fire-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50382.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5445</span> Investigating a Modern Accident Analysis Model for Textile Building Fires through Numerical Reconstruction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsin%20Ali%20Shaikh">Mohsin Ali Shaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiguo%20Song"> Weiguo Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Rehmat%20Karim"> Rehmat Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Kashan%20Surahio"> Muhammad Kashan Surahio</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Usman%20Shahid"> Muhammad Usman Shahid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fire investigations face challenges due to the complexity of fire development, and real-world accidents lack repeatability, making it difficult to apply standardized approaches. The unpredictable nature of fires and the unique conditions of each incident contribute to the complexity, requiring innovative methods and tools for effective analysis and reconstruction. This study proposes to provide the modern accident analysis model through numerical reconstruction for fire investigation in textile buildings. This method employs computer simulation to enhance the overall effectiveness of textile-building investigations. The materials and evidence collected from past incidents reconstruct fire occurrences, progressions, and catastrophic processes. The approach is demonstrated through a case study involving a tragic textile factory fire in Karachi, Pakistan, which claimed 257 lives. The reconstruction method proves invaluable for determining fire origins, assessing losses, establishing accountability, and, significantly, providing preventive insights for complex fire incidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20investigation" title="fire investigation">fire investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20safety" title=" fire safety"> fire safety</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20incident" title=" fire incident"> fire incident</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20building" title=" textile building"> textile building</a> </p> <a href="https://publications.waset.org/abstracts/177599/investigating-a-modern-accident-analysis-model-for-textile-building-fires-through-numerical-reconstruction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177599.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">65</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5444</span> Fire and Explosion Consequence Modeling Using Fire Dynamic Simulator: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iftekhar%20%20Hassan">Iftekhar Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayedil%20Morsalin"> Sayedil Morsalin</a>, <a href="https://publications.waset.org/abstracts/search?q=Easir%20A%20Khan"> Easir A Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accidents involving fire occur frequently in recent times and their causes showing a great deal of variety which require intervention methods and risk assessment strategies are unique in each case.

FDS is an advanced computational fluid dynamics (CFD) system of fire-driven fluid flow which solves numerically a large eddy simulation form of the Navier–Stokes’s equations for simulation of the fire and smoke spread and prediction of thermal radiation, toxic substances concentrations and other relevant parameters of fire. This study focuses on understanding the nature of the fire and consequence evaluation due to thermal radiation caused by vapor cloud explosion. An evacuation modeling was constructed to visualize the effect of evacuation time and fractional effective dose (FED) for different types of agents. The results were presented by 3D animation, sliced pictures and graphical representation to understand fire hazards caused by thermal radiation or smoke due to vapor cloud explosion. This study will help to design and develop appropriate respond strategy for preventing similar accidents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consequence%20modeling" title="consequence modeling">consequence modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20and%20explosion" title=" fire and explosion"> fire and explosion</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20dynamics%20simulation%20%28FDS%29" title=" fire dynamics simulation (FDS)"> fire dynamics simulation (FDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20radiation" title=" thermal radiation "> thermal radiation </a> </p> <a href="https://publications.waset.org/abstracts/136628/fire-and-explosion-consequence-modeling-using-fire-dynamic-simulator-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">225</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5443</span> An Operators’ Real-sense-based Fire Simulation for Human Factors Validation in Nuclear Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sa-Kil%20Kim">Sa-Kil Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang-Soo%20Lee"> Jang-Soo Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On March 31, 1993, a severe fire accident took place in a nuclear power plant located in Narora in North India. The event involved a major fire in the turbine building of NAPS unit-1 and resulted in a total loss of power to the unit for 17 hours. In addition, there was a heavy ingress of smoke in the control room, mainly through the intake of the ventilation system, forcing the operators to vacate the control room. The Narora fire accident provides us lessons indicating that operators could lose their mind and predictable behaviors during a fire. After the Fukushima accident, which resulted from a natural disaster, unanticipated external events are also required to be prepared and controlled for the ultimate safety of nuclear power plants. From last year, our research team has developed a test and evaluation facility that can simulate external events such as an earthquake and fire based on the operators’ real-sense. As one of the results of the project, we proposed a unit real-sense-based facility that can simulate fire events in a control room for utilizing a test-bed of human factor validation. The test-bed has the operator’s workstation shape and functions to simulate fire conditions such as smoke, heat, and auditory alarms in accordance with the prepared fire scenarios. Furthermore, the test-bed can be used for the operators’ training and experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20behavior%20in%20fire" title="human behavior in fire">human behavior in fire</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20factors%20validation" title=" human factors validation"> human factors validation</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20plants" title=" nuclear power plants"> nuclear power plants</a>, <a href="https://publications.waset.org/abstracts/search?q=real-sense-based%20fire%20simulation" title=" real-sense-based fire simulation"> real-sense-based fire simulation</a> </p> <a href="https://publications.waset.org/abstracts/50329/an-operators-real-sense-based-fire-simulation-for-human-factors-validation-in-nuclear-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50329.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5442</span> Improving Fire Resistance of Wood and Wood-Based Composites and Fire Testing Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadir%20Ayrilmis">Nadir Ayrilmis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood and wood-based panels are one of the oldest structural materials used in the construction industry due to their significant advantages such as good mechanical properties, low density, renewable material, low-cost, recycling, etc. However, they burn when exposed to a flame source or high temperatures.

People here in Egypt did not consider the safety and fire protection as important as it is. But on the other hand, its very important for them to contain the fire systems and safety in every facility, the companies , hospitals , police stations , and even the super markets must use the fire system. It makes the facility safe to the visitors while they are using it.From my point of view as the owner Fire Safety Company called Deluge Egypt , i can say that not all of the companies use the fire system protection according to the high cost they prefer to build their company without the protection, and this is make the building totally unsafe to be used from the visitors or client.So, i am looking for new methods and technology to invest in Egypt, and this is through attending this Conference and let the audiences know more about the services i provide and [to let them know about the importance of the Fire Safety in Egypt. The Objectives of my research 1- The system that i used in my Company. 2- The benefits of the Fire System Protection. 3-The importance of the Fire System and safety. 4-The use of the new Technologies. 5-The hardships that i found while having new deals with new clients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire" title="fire">fire</a>, <a href="https://publications.waset.org/abstracts/search?q=system" title=" system"> system</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20hydrants" title=" fire hydrants"> fire hydrants</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=alarms" title=" alarms"> alarms</a> </p> <a href="https://publications.waset.org/abstracts/171993/the-importance-of-fire-safety-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171993.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5440</span> Prediction of the Heat Transfer Characteristics of Tunnel Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seung%20Cho%20Yang">Seung Cho Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Sung%20Lee"> Jae Sung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Se%20Hee%20Park"> Se Hee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study suggests the analysis method to predict the damages of tunnel concrete caused by fires.

After an earthquake, fire is possible in structures. In this research, the effect of post-earthquake fire on steel moment frames with and without fireproofing coating is investigated. For this purpose, finite element method is employed. For the verification of finite element results, the results of an experimental study carried out by previous researchers are used, and the predicted FE results are compared with the test results, and good agreement is observed. After ensuring the accuracy of the predictions of finite element models, the effect of post-earthquake fire on the frames is investigated taking into account the parameters including the presence or absence of fire protection, frame design assumptions, earthquake type and different fire scenario. Ordinary fire and post-earthquake fire effect on the frames is also studied. The plastic hinges induced by earthquake in the structure are determined in the beam to the column connection and in panel zone. These areas should be accurately considered when providing fireproofing coatings. The results of the study show that the occurrence of fire beside corner columns is the most damaging scenario that results in progressive collapse of structure. It was also concluded that the behavior of structure in fire after a strong ground motion is significantly different from that in a normal fire. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post%20earthquake%20fire" title="post earthquake fire">post earthquake fire</a>, <a href="https://publications.waset.org/abstracts/search?q=moment%20frame" title=" moment frame"> moment frame</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20simulation" title=" finite element simulation"> finite element simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20temperature-displacement%20analysis" title=" coupled temperature-displacement analysis"> coupled temperature-displacement analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20scenario" title=" fire scenario"> fire scenario</a> </p> <a href="https://publications.waset.org/abstracts/98372/a-study-on-the-failure-modes-of-steel-moment-frame-in-post-earthquake-fire-using-coupled-mechanical-thermal-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5438</span> The Effect of Water Droplets Size in Fire Fighting Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tassadit%20Tabouche">Tassadit Tabouche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water sprays pattern, and water droplets size (different droplets diameter) are a key factors in the success of the suppression by water spray.

Two fires models are achieved. The first one is a zone model realized with the CFAST software. Then, this fire is imported in a building EXODUS model in order to determine the evacuation time with effects of fire effluents (temperature, smoke opacity, smoke toxicity) on passengers. The second fire is achieved with Fire Dynamics Simulator software. The fire defined is directly imported in the FDS+Evac model which will permit to determine the evacuation time and effects of fire effluents on passengers. These effects will be compared with tenability criteria defined in some standards in order to see if the situation is acceptable. Different power of fire will be underlined to see from what power source the hazard become unacceptable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20safety%20engineering" title="fire safety engineering">fire safety engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20tools" title=" numerical tools"> numerical tools</a>, <a href="https://publications.waset.org/abstracts/search?q=rolling%20stock" title=" rolling stock"> rolling stock</a>, <a href="https://publications.waset.org/abstracts/search?q=evacuation" title=" evacuation"> evacuation</a> </p> <a href="https://publications.waset.org/abstracts/73910/impact-of-an-onboard-fire-for-the-evacuation-of-a-rolling-stock" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73910.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5436</span> An Experimental Study on the Optimum Installation of Fire Detector for Early Stage Fire Detecting in Rack-Type Warehouses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ki%20Ok%20Choi">Ki Ok Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Ho%20Hong"> Sung Ho Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Suck%20Kim"> Dong Suck Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Don%20Mook%20Choi"> Don Mook Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rack type warehouses are different from general buildings in the kinds, amount, and arrangement of stored goods, so the fire risk of rack type warehouses is different from those buildings. The fire pattern of rack type warehouses is different in combustion characteristic and storing condition of stored goods. The initial fire burning rate is different in the surface condition of materials, but the running time of fire is closely related with the kinds of stored materials and stored conditions. The stored goods of the warehouse are consisted of diverse combustibles, combustible liquid, and so on. Fire detection time may be delayed because the residents are less than office and commercial buildings. If fire detectors installed in rack type warehouses are inadaptable, the fire of the warehouse may be the great fire because of delaying of fire detection. In this paper, we studied what kinds of fire detectors are optimized in early detecting of rack type warehouse fire by real-scale fire tests. The fire detectors used in the tests are rate of rise type, fixed type, photo electric type, and aspirating type detectors. We considered optimum fire detecting method in rack type warehouses suggested by the response characteristic and comparative analysis of the fire detectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20detector" title="fire detector">fire detector</a>, <a href="https://publications.waset.org/abstracts/search?q=rack" title=" rack"> rack</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20characteristic" title=" response characteristic"> response characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=warehouse" title=" warehouse"> warehouse</a> </p> <a href="https://publications.waset.org/abstracts/56376/an-experimental-study-on-the-optimum-installation-of-fire-detector-for-early-stage-fire-detecting-in-rack-type-warehouses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56376.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">745</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5435</span> Prediction of Fire Growth of the Office by Real-Scale Fire Experiment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kweon%20Oh-Sang">Kweon Oh-Sang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kim%20Heung-Youl"> Kim Heung-Youl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Estimating the engineering properties of fires is important to be prepared for the complex and various fire risks of large-scale structures such as super-tall buildings, large stadiums, and multi-purpose structures.

The procedure has been added to the software package Abaqus/Standard as a user-defined subroutine (UMATHT) and has been verified using both time-and spatially dependent heat fluxes in two- and three-dimensional problems. The aim is to contribute to the development of simulation tools needed to assist structural engineers and fire testing laboratories in technical assessment exercises. The presented method can also be used under the developmental stages of building components to optimize performance in real fire conditions. The accuracy of the used thermal properties and the finite element models was validated by comparing the predicted results with three different available fire tests in literature. It was found that the model calibrated to results from standard fire conditions provided reasonable predictions of temperatures within assemblies exposed to real building fire. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timber%20panels" title="Timber panels">Timber panels</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20fire%20tests" title=" standard fire tests"> standard fire tests</a> </p> <a href="https://publications.waset.org/abstracts/58263/numerical-analysis-of-fire-performance-of-timber-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58263.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5433</span> A Small-Scale Study of Fire Whirls and Investigation of the Effects of Near-Ground Height on the Behavior of Fire Whirls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Arabghahestani">M.

High speed imaging was used to track the flames at both temporal and spatial scales. This allowed us to better understand the role of the near-ground height in creating a boundary layer flow profile that, in turn contributes to formation of vortices around the fire, and consequent fire whirls. Based on the results obtained from these observations, we were able to spot the differences in the fuel burning rate of the fire itself as a function of a newly defined specific non-dimensional near-ground height. Based on our observations, there is a cutoff non-dimensional height, beyond which a normal fire can be turned into a fire whirl. Additionally, the results showed that the fire burning rate decreases by moving the fire to a height higher than the ground level. These effects were justified by the interactions between vortices formed by, the back pressure and the boundary layer velocity profile, and the vortices generated by the fire itself. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer%20profile" title="boundary layer profile">boundary layer profile</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20whirls" title=" fire whirls"> fire whirls</a>, <a href="https://publications.waset.org/abstracts/search?q=near-ground%20height" title=" near-ground height"> near-ground height</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20interactions" title=" vortex interactions"> vortex interactions</a> </p> <a href="https://publications.waset.org/abstracts/107924/a-small-scale-study-of-fire-whirls-and-investigation-of-the-effects-of-near-ground-height-on-the-behavior-of-fire-whirls" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107924.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5432</span> Forest Fire Risk Mapping Using Analytic Hierarchy Process and GIS-Based Application: A Case Study in Hua Sai District, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narissara%20Nuthammachot">Narissara Nuthammachot</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitris%20Stratoulias"> Dimitris Stratoulias</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fire is one of the main causes of environmental and ecosystem change. Therefore, it is a challenging task for fire risk assessment fire potential mapping. The study area is Hua Sai district, Nakorn Sri Thammarat province, which covers in a part of peat swamp forest areas. 55 fire points in peat swamp areas were reported from 2012 to 2016. Analytic Hierarchy Process (AHP) and Geographic Information System (GIS) methods were selected for this study. The risk fire area map was arranged on these factors; elevation, slope, aspect, precipitation, distance from the river, distance from town, and land use. The results showed that the predicted fire risk areas are found to be in appreciable reliability with past fire events.

Concrete’s inherent ability to combat one of the most devastating disaster that a structure can endure in its lifetime, can be attributed to its constituent materials which make it inert and have relatively poor thermal conductivity. However, concrete structures must be designed for fire effects. Structural components should be able to withstand dead and live loads without undergoing collapse. The properties of high-strength concrete must be weighed against concerns about its fire resistance and susceptibility to spalling at elevated temperatures. In this paper, the causes, effects and some remedy of deterioration in concrete due to fire hazard will be discussed. Some cost effective solutions to produce a fire resistant concrete will be conversed through this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=spalling" title=" spalling"> spalling</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a> </p> <a href="https://publications.waset.org/abstracts/41154/a-review-on-concrete-structures-in-fire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41154.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">443</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5430</span> Emissivity Analysis of Hot-Dip Galvanized Steel in Fire </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Gaigl">Christian Gaigl</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Mensinger"> Martin Mensinger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Once a fire resistance rating is necessary, it has to be proofed that the load bearing behavior of a steel construction under the exposure of fire still fits the static demands. High costs of passive fire protection, which satisfies the requirements, frequently result in a concrete solution. To optimize these expenses, one method is to determine the critical temperature according to the Eurocode DIN EN 1993-1-2. For this purpose, positive effects of hot-dip galvanized surface layers on the temperature development of steel members in the accidental situation of fire exposure has been investigated. The test results show a significant better heating behavior of hot-dip galvanized steel components compared to normal steel specimen. This leads in many cases to a R30 (30 minutes of ISO-fire) fire protection requirement of unprotected steel members and therefore to an economic added value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20resistance" title="fire resistance">fire resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=hot-dip%20galvanizing" title=" hot-dip galvanizing"> hot-dip galvanizing</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20constructions" title=" steel constructions"> steel constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=R30%20requirement" title=" R30 requirement"> R30 requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=emissivity" title=" emissivity"> emissivity</a> </p> <a href="https://publications.waset.org/abstracts/94148/emissivity-analysis-of-hot-dip-galvanized-steel-in-fire" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94148.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5429</span> Simulation of Forest Fire Using Wireless Sensor Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20F.%20Fauzi">Mohammad F.

The hot climate in Brunei Darussalam can lead to forest fires which can be a fatal threat to the preservation of our forest. The process consists of getting data from the sensors, analyzing the data and producing an alert.

The uniqueness of the stadium is that spectators can have an unobstructed view from all around the podium towards the field of play. Upper and lower bowls are connected by stairs. The stairs landing is a precast slab supported by cantilevered steel beams. These steel beams are fixed to precast columns supporting the stadium structure. The stair slabs are precast concrete supported on a landing slab and cantilevered steel beams. During an event of a fire at podium level between two staircases, fire resistance of steel beams is very critical to life safety. If the steel beam loses its strength due to lack of fire resistance, it will be weak in supporting stair slabs and may lead to a hazard in evacuating occupants from the upper bowl to the lower bowl. In this study, to ascertain fire rating and life safety, a performance-based design using CFD analysis is used to evaluate the steel beams' fire resistance. A fire size of 3.5 MW (convective heat output of fire) with a wind speed of 2.57 m/s is considered for fire and smoke simulation. CFD results show that the smoke temperature near the staircase/ around the staircase does not exceed 1500 C for the fire duration considered. The surface temperature of cantilevered steel beams is found to be less than or equal to 1500 C. Since this temperature is much less than the critical failure temperature of steel (5200 C), it is concluded that the design of structural steel supports on the staircase is adequate and does not need additional fire protection such as fire-resistant coating. CFD analysis provided an engineering basis for the performance-based design of steel structural elements and an opportunity to optimize fire protection requirements. Thus, performance-based design using CFD modeling and simulation of fire and smoke is an innovative way to evaluate fire rating requirements, ascertain life safety and optimize the design with regard to fire protection on structural steel elements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20resistance" title="fire resistance">fire resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20safety" title=" life safety"> life safety</a>, <a href="https://publications.waset.org/abstracts/search?q=performance-based%20design" title=" performance-based design"> performance-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20analysis" title=" CFD analysis"> CFD analysis</a> </p> <a href="https://publications.waset.org/abstracts/139633/engineering-analysis-for-fire-safety-using-computational-fluid-dynamic-cfd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139633.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5427</span> Failure Probability Assessment of Concrete Spherical Domes Subjected to Ventilation Controlled Fires Using BIM Tools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20T.%20Kassem">A.

Most buildings’ structural elements are designed, taking into consideration precautions for fire safety, using deterministic design approaches. Public and highly important buildings are commonly designed considering standard fire rating and, in many cases, contain large compartments with central domes. Real fire scenarios are not commonly brought into action in structural design of buildings because of complexities in both scenarios and analysis tools. This paper presents a modern approach towards analysis of spherical domes in real fire condition via implementation of building information modelling, and adopting a probabilistic approach. BIMhas been implemented to bridge the gap between various software packages enabling them to function interactively to model both real fire and corresponding structural response. Ventilation controlled fires scenarios have been modeled using both “Revit” and “Pyrosim”. Monte Carlo simulation has been adopted to engage the probabilistic analysis approach in dealing with various parameters. Conclusions regarding failure probability and fire endurance, in addition to the effects of various parameters, have been extracted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete" title="concrete">concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=spherical%20domes" title=" spherical domes"> spherical domes</a>, <a href="https://publications.waset.org/abstracts/search?q=ventilation%20controlled%20fires" title=" ventilation controlled fires"> ventilation controlled fires</a>, <a href="https://publications.waset.org/abstracts/search?q=BIM" title=" BIM"> BIM</a>, <a href="https://publications.waset.org/abstracts/search?q=monte%20carlo%20simulation" title=" monte carlo simulation"> monte carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=pyrosim" title=" pyrosim"> pyrosim</a>, <a href="https://publications.waset.org/abstracts/search?q=revit" title=" revit"> revit</a> </p> <a href="https://publications.waset.org/abstracts/141926/failure-probability-assessment-of-concrete-spherical-domes-subjected-to-ventilation-controlled-fires-using-bim-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141926.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5426</span> Predicting Root Cause of a Fire Incident through Transient Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mira%20Ezora%20Zainal%20Abidin">Mira Ezora Zainal Abidin</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Fauzuna%20Othman"> Siti Fauzuna Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Zalina%20Harun"> Zalina Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Hafiz%20M.%20Pikri"> M. Hafiz M. Pikri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In a fire incident involving a Nitrogen storage tank that over-pressured and exploded, resulting in a fire in one of the units in a refinery, lack of data and evidence hampered the investigation to determine the root cause. Instrumentation and fittings were destroyed in the fire. To make it worst, this incident occurred during the COVID-19 pandemic, making collecting and testing evidence delayed. In addition to that, the storage tank belonged to a third-party company which requires legal agreement prior to the refinery getting approval to test the remains. Despite all that, the investigation had to be carried out with stakeholders demanding answers. The investigation team had to devise alternative means to support whatever little evidence came out as the most probable root cause. International standards, practices, and previous incidents on similar tanks were referred. To narrow down to just one root cause from 8 possible causes, transient simulations were conducted to simulate the overpressure scenarios to prove and eliminate the other causes, leaving one root cause. This paper shares the methodology used and details how transient simulations were applied to help solve this. The experience and lessons learned gained from the event investigation and from numerous case studies via transient analysis in finding the root cause of the accident leads to the formulation of future mitigations and design modifications aiming at preventing such incidents or at least minimize the consequences from the fire incident. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire" title="fire">fire</a>, <a href="https://publications.waset.org/abstracts/search?q=transient" title=" transient"> transient</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=relief" title=" relief"> relief</a> </p> <a href="https://publications.waset.org/abstracts/166904/predicting-root-cause-of-a-fire-incident-through-transient-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166904.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5425</span> Effect of Fire Exposure on the Ultimate Strength of Loaded Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Hamdy%20Ghieth">Hatem Hamdy Ghieth</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the recent time many fires happened in many skeleton buildings.

A fire experiment with jatropha oil was conducted in a compartment of size 4 m x 4 m x m to study the fire development and temperature distribution. Fuel is burned in the center of the compartment in a pool diameter of 0.5 m with an initial fuel depth of 0.045 m. Corner temperature in the compartment, doorway temperature and hot gas layer temperature at various locations are measured. Numerical simulations were carried out using Fire Dynamics Simulator (FDS) software at grid size of 0.05 m, 0.12 m and for performing simulation heat release rate of jatropha oil measured using mass loss method were inputted into FDS. Experimental results shows that like other fuel fires, the whole combustion process can be divided into four stages: initial stage, growth stage, steady profile or developed phase and decay stage. The fire behavior shows two zone profile where upper zone consists of mainly hot gases while lower zone is relatively at colder side. In this study, predicted temperatures from simulation are in good agreement in upper zone of compartment. Near the interface of hot and cold zone, deviations were reported between the simulated and experimental results which is probably due to the difference between the predictions of smoke layer height by FDS. Also, changing the grid size from 0.12 m to 0.05 m does not show any effect in temperatures at upper zone while in lower zone, grid size of 0.05 m showed satisfactory agreement with experimental results. Numerical results showed that calculated temperatures at various locations matched well with the experimental results. On the whole, an effective method is provided with reasonable results to study the burning characteristics of jatropha oil with numerical simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=jatropha%20oil" title="jatropha oil">jatropha oil</a>, <a href="https://publications.waset.org/abstracts/search?q=compartment%20fire" title=" compartment fire"> compartment fire</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20release%20rate" title=" heat release rate"> heat release rate</a>, <a href="https://publications.waset.org/abstracts/search?q=FDS%20%28fire%20dynamics%20simulator%29" title=" FDS (fire dynamics simulator)"> FDS (fire dynamics simulator)</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/72894/numerical-study-on-jatropha-oil-pool-fire-behavior-in-a-compartment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72894.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5423</span> Accidental Compartment Fire Dynamics: Experiment, Computational Fluid Dynamics Weakness and Expert Interview Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20Onyenobi">Timothy Onyenobi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accidental fires and its dynamic as it relates to building compartmentation and the impact of the compartment morphology, is still an on-going area of study; especially with the use of computational fluid dynamics (CFD) modeling methods. With better knowledge on this subject come better solution recommendations by fire engineers. Interviews were carried out for this study where it was identified that the response perspectives to accidental fire were different with the fire engineer providing qualitative data which is based on “what is expected in real fires” and the fire fighters provided information on “what actually obtains in real fires”. This further led to a study and analysis of two real and comprehensively instrumented fire experiments: the Open Plan Office Project by National Institute of Standard and Technology (NIST) USA (to study time to flashover) and the TF2000 project by the Building Research Establishment (BRE) UK (to test for conformity with Building Regulation requirements). The findings from the analysis of the experiments revealed the relative yet critical weakness of fire prediction using a CFD model (usually used by fire engineers) as well as explained the differences
