The results show any increase in both cold mass fraction and inlet pressure caused to increase ΔTc, and the maximum ΔTc value occurs at P = 6 bar. The coefficient of performance (COP) of two important factors in the vortex tube have been evaluated, which ranged from 0.25 to 0.74. The maximum axial velocity is 93, where it occurs at the tube axis close the inlet exit (Z/L=0.2).

Determination of the safety of masonry structures against earthquakes is a complex challenge. This study deals with experimental tests and non-linear dynamic analysis of masonry structures modeled through discrete element method. The 1:10 scale model of Mustafa Paşa Mosque was constructed and the data were obtained from the sensors on it during its testing on the shake table. The results were used in the calibration/validation of the numerical model created on the basis of the 1:10 scale model built for shake table testing. 3D distinct element model was developed that represents the linear and nonlinear behavior of the shake table model as closely as possible during experimental tests. Results of numerical analyses with those from the experimental program were compared and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20analysis" title="dynamic analysis">dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20modeling" title=" non-linear modeling"> non-linear modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=shake%20table%20tests" title=" shake table tests"> shake table tests</a>, <a href="https://publications.waset.org/abstracts/search?q=masonry" title=" masonry"> masonry</a> </p> <a href="https://publications.waset.org/abstracts/30824/experimental-and-numerical-analysis-of-mustafa-pasa-mosque-in-skopje" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30824.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">425</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">34490</span> On the Numerical and Experimental Analysis of Internal Pressure in Air Bearings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdurrahim%20Dal">Abdurrahim Dal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuncay%20Kara%C3%A7ay"> Tuncay Karaçay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dynamics of a rotor supported by air bearings is strongly depends on the pressure distribution between the rotor and the bearing. In this study, internal pressure in air bearings is numerical and experimental analyzed for different radial clearances. Firstly the pressure distribution between rotor and bearing is modeled using Reynold's equation and this model is solved numerically. The rotor-bearing system is also modeled in four degree of freedom and it is simulated for different radial clearances. Then, in order to validate numerical results, a test rig is designed and the rotor bearing system is run under the same operational conditions. Pressure signals of left and right bearings are recorded.

A jet Reynolds number (Rₑ) of 10,000, jet-to- plate spacing (H/D) of two and eight and two angles of impingement (α) of 45° and 90° (orthogonal) were employed in this study. An unconfined jet impinges steadily a constant temperature flat surface using air as working fluid. The numerical investigation is validated with an experimental study. This numerical study employs grid dependency investigation and four different types of turbulence models including the transition SSD to accurately predict the second local maximum in Nusselt number. A full analysis of the effect of both turbulence models and mesh size is reported. Numerical values showed excellent agreement with the experimental data for the case of orthogonal impingement. For the case of H/D =6 and α=45° a maximum percentage error of approximately 8.8% occurs of local Nusselt number at stagnation point.

Given the scarcity of studies exploring high-velocity impacts on concrete, the primary aim of this research is to scrutinize how concrete behaves under high-speed impacts, ultimately contributing valuable insights to the development of protective structures. To achieve this objective, a comprehensive numerical analysis was carried out in LS-DYNA to delve into the fracture mechanisms inherent in concrete under such extreme conditions. Subsequently, the obtained numerical outcomes were compared and validated through eight experimental field tests. The methodology employed involved a robust combination of numerical simulations and real-world experiments, ensuring a comprehensive understanding of concrete behavior in scenarios involving rapid, high-energy impacts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-velocity" title="high-velocity">high-velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20tests" title=" experimental tests"> experimental tests</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a> </p> <a href="https://publications.waset.org/abstracts/180950/analysis-of-high-velocity-impacts-on-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180950.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">86</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">34487</span> Experimental Study Damage in a Composite Structure by Vibration Analysis- Glass / Polyester</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Abdeldjebar">R.

The experimental tests were focused on the vibrations which occur inside of the rod element during functionality of the oil pump unit. The oil pump mechanism dynamic parameters were measured and also determined through numerical computations. Entire research is based on the oil pump unit mechanical system virtual prototyping. For a complete analysis of the mechanism, the frequency dynamic response was identified, mainly for the mechanism driven element, based on two methods: processing and virtual simulations with MSC Adams aid and experimental analysis. In fact, through this research, a complete methodology is presented where numerical simulations of a mechanism with deformed elements are developed on a dynamic mode and these can be correlated with experimental tests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modal%20dynamic%20analysis" title="modal dynamic analysis">modal dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20pump" title=" oil pump"> oil pump</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrations" title=" vibrations"> vibrations</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20elements" title=" flexible elements"> flexible elements</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20response" title=" frequency response"> frequency response</a> </p> <a href="https://publications.waset.org/abstracts/47941/modal-dynamic-analysis-of-a-mechanism-with-deformable-elements-from-an-oil-pump-unit-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47941.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">319</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">34485</span> Experimental and Numerical Processes of Open Die Forging of Multimetallic Materials with the Usage of Different Lubricants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isik%20Cetintav">Isik Cetintav</a>, <a href="https://publications.waset.org/abstracts/search?q=Cenk%20Misirli"> Cenk Misirli</a>, <a href="https://publications.waset.org/abstracts/search?q=Yilmaz%20Can"> Yilmaz Can</a>, <a href="https://publications.waset.org/abstracts/search?q=Damla%20Gunel"> Damla Gunel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigates experimental and numerical analysis of open die forging of multimetallic materials.

Furthermore, in this work, the mechanical properties of multimetallic metallic materials produced using different materials will be examined by using different lubricants. The advantages and disadvantages of different lubricants will be approached with the bi-metallic material to be produced. Cylindrical specimens consisting of two different materials were used in the experiments. Specimens were prepared as aluminum sleeve and copper core and upset at different reduction.

Also, they allow reducing the speed of rotation, the radial spacing and a better flexibility of use. However, this requires a better understanding of their operation, including the influence of second rotor on the overall aerodynamic performances. This work consisted of both experimental and numerical studies to characterize this counter-rotating fan, especially the analysis of the effects of the blades stagger angle and the inter-distance between the rotors. The experimental study served to validate the computational fluid dynamics model (CFD) used in the simulations. The numerical study permitted to cover a wider range of parameter and deeper investigation on flow structures details, including the effects of blade stagger angle and inter-distance, associated with the interaction between the rotors. As a result, there is a clear improvement in aerodynamic performance compared with a conventional machine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20performance" title="aerodynamic performance">aerodynamic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20fan" title=" axial fan"> axial fan</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20rotating%20rotors" title=" counter rotating rotors"> counter rotating rotors</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20study" title=" experimental study"> experimental study</a> </p> <a href="https://publications.waset.org/abstracts/107619/numerical-and-experimental-investigation-of-the-aerodynamic-performances-of-counter-rotating-rotors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107619.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">159</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">34481</span> Numerical and Experimental Analysis of Temperature Distribution and Electric Field in a Natural Rubber Glove during Microwave Heating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20Narumitbowonkul">U.

The coupled equations of electromagnetic wave propagation and heat transfer are solved using the finite element method (FEM). The numerical model is validated with an experimental study at a frequency of 2.45 GHz. The results show that the numerical results closely match the experimental results. Furthermore, it is found that the temperature distribution and electric field increases with increasing heating time. The hot spot zone appears in NRG at the tip of middle finger while the maximum temperature occurs in case of rotation angle of NRG = 60 degree.

Punching failure is brittle in nature which induces more vulnerability to this type of structure. In the present study, a 3D finite element model of a flat plate with low reinforcement ratio and without any transverse reinforcement has been developed. Punching shear stress and the deflection data were obtained on the surface of the flat plate as well as through the thickness of the model from numerical simulations. The obtained data were compared with the experimental results. Variation of punching stress with respect to deflection as obtained from numerical results is found to be in good agreement with the experimental results; the range of variation of punching stress is within 5%. The numerical simulation shows an early and gradual onset of nonlinearity, whereas the same is late and abrupt as observed in the experimental results. The range of variation of punching stress for different slab thicknesses between experimental and numerical results is less than 15%. The developed numerical model is useful to complement available punching test series performed in the past. The results obtained from the numerical model will be helpful for designing retrofitting schemes of flat plates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flat%20plate" title="flat plate">flat plate</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20model" title=" finite element model"> finite element model</a>, <a href="https://publications.waset.org/abstracts/search?q=punching%20shear" title=" punching shear"> punching shear</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20ratio" title=" reinforcement ratio"> reinforcement ratio</a> </p> <a href="https://publications.waset.org/abstracts/45233/numerical-simulation-of-punching-shear-of-flat-plates-with-low-reinforcement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45233.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">34478</span> Experimental and Numerical Analysis of Built-In Thermoelectric Generator Modules with Elliptical Pin-Fin Heat Sink</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Y%20%20Jang">J.

The TEG module consists of a thermoelectric generator, an elliptical pin-fin heat sink, and a cold plate for water cooling. In the chimney, the temperature of flue gases is 450-650K. Therefore, the effects of convection and radiation heat transfer are considered. Although the TEG hot-side temperature and thus the electric power output can be increased by inserting an elliptical pin-fin heat sink into the chimney tunnel to increase the heat transfer area, the pin fin heat sink would cause extra pumping power at the same time. The main purpose of this study is to analyze the effects of geometrical parameters on the electric power output and chimney pressure drop characteristics. In addition, the effects of different operating conditions, including various inlet velocities (Vin = 1, 3, 5 m/s) and inlet temperatures (Tgas = 450, 550, 650K) are discussed in detail. The predicted numerical data for the power vs. current (P-I) curve are in good agreement (within 11%) with the experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20generator" title="thermoelectric generator">thermoelectric generator</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=pin-fin%20heat%20sink" title=" pin-fin heat sink"> pin-fin heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20and%20numerical%20analysis" title=" experimental and numerical analysis"> experimental and numerical analysis</a> </p> <a href="https://publications.waset.org/abstracts/13661/experimental-and-numerical-analysis-of-built-in-thermoelectric-generator-modules-with-elliptical-pin-fin-heat-sink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13661.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">382</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">34477</span> Design and Manufacture of Non-Contact Moving Load for Experimental Analysis of Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Firooz%20Bakhtiari-Nejad">Firooz Bakhtiari-Nejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Rostami"> Hamidreza Rostami</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Mirzaee"> Meysam Mirzaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Zandbaf"> Mona Zandbaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dynamic tests are an important step of the design of engineering structures, because the accuracy of predictions of theoretical–numerical procedures can be assessed. In experimental test of moving loads that is one of the major research topics, the load is modeled as a simple moving mass or a small vehicle. This paper deals with the applicability of Non-Contact Moving Load (NML) for vibration analysis. For this purpose, an experimental set-up is designed to generate the different types of NML including constant and harmonic. The proposed method relies on pressurized air which is useful, especially when dealing with fragile or sensitive structures. To demonstrate the performance of this system, the set-up is employed for a modal analysis of a beam and detecting crack of the beam. The obtained results indicate that the experimental set-up for NML can be an attractive alternative to the moving load problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20analysis" title="experimental analysis">experimental analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20load" title=" moving load"> moving load</a>, <a href="https://publications.waset.org/abstracts/search?q=non-contact%20excitation" title=" non-contact excitation"> non-contact excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20engineering" title=" materials engineering"> materials engineering</a> </p> <a href="https://publications.waset.org/abstracts/2510/design-and-manufacture-of-non-contact-moving-load-for-experimental-analysis-of-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2510.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">465</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">34476</span> Analysis of Flexural Behavior of Wood-Concrete Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Li">M.

The impact problems (penetration and perforation) of the metallic plates have been of interest for a long time. Experimental, analytical as well as numerical studies have been carried out to analyze in details the perforation process. Based on these approaches, the ballistic properties of the material have been studied. The initial and residual velocities laser sensor is used during experiments to obtain the ballistic curve and the ballistic limit. The energy balance is also reported together with the energy absorbed by the aluminum including the ballistic curve and ballistic limit. The high speed camera helps to estimate the failure time and to calculate the impact force. A wide range of initial impact velocities from 40 up to 180 m/s has been covered during the tests. The mass of the conical nose shaped projectile is 28 g, its diameter is 12 mm, and the thickness of the aluminum sheet is equal to 1.0 mm. The ABAQUS/Explicit finite element code has been used to simulate the perforation processes. The comparison of the ballistic curve was obtained numerically and was verified experimentally, and the failure patterns are presented using the optimal mesh densities which provide the stability of the results. A good agreement of the numerical and experimental results is observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20alloy" title="aluminum alloy">aluminum alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=ballistic%20behavior" title=" ballistic behavior"> ballistic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20criterion" title=" failure criterion"> failure criterion</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/60677/perforation-analysis-of-the-aluminum-alloy-sheets-subjected-to-high-rate-of-loading-and-heated-using-thermal-chamber-experimental-and-numerical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60677.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">312</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">34474</span> Numerical Approach of RC Structural MembersExposed to Fire and After-Cooling Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ju-young%20Hwang">Ju-young Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo-Gyoung%20Kwak"> Hyo-Gyoung Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Jae%20Yim"> Hong Jae Yim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces a numerical analysis method for reinforced-concrete (RC) structures exposed to fire and compares the result with experimental results.

Composites are prone to failures or damages that are difficult to identify, locate, and characterize due to their complex design features and complicated loading conditions. The lack of understanding of the damage mechanism of the composites leads to the uncertainties in the structural integrity and durability. Delamination is one of the most critical failure mechanisms in laminated composites because it progressively affects the mechanical performance of fiber-reinforced polymer composite structures over time. The identification and severity characterization of delamination in engineering fields such as the aviation industry is critical for both safety and economic concerns. The presence of delamination alters the vibration properties of composites, such as natural frequencies, mode shapes, and so on. In this study, numerical analysis and experimental analysis were performed on delaminated and non-delaminated glass fiber reinforced polymer (GFRP) plate, and the numerical and experimental analysis results were compared, and error percentage has been found out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composites" title="composites">composites</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title=" natural frequency"> natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20shapes" title=" mode shapes"> mode shapes</a> </p> <a href="https://publications.waset.org/abstracts/151026/experimental-and-numerical-investigation-on-delaminated-composite-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151026.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">108</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">34471</span> Effects of Repeated High Loadings on the Performance of Adhesively-Bonded Single Lap Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orkun%20Yavuz">Orkun Yavuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Kadio%C4%9Flu"> Ferhat Kadioğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Emin%20Ercan"> M.

A projectile with a mass of 1.25 gr and density of 11.3 gr/cm3 was fired at the joints with a velocity of about 280 m/s using a specially designed experimental set-up, and the impact was recorded via a high-speed camera. The SLJs were manufactured from 6061 aluminum adherend (AA6061) material and an adhesive film. The joints, which have an adherend thickness of 4 mm and overlap length of 15 mm, were subjected to up to 3 shots for the ballistic test, followed by quasi-static tensile testing. The impacted joints, then, were compared to the non-impacted and one-shot impacted ones, which was a subject of investigation carried out before. It was found that while the joints subjected to 2 shots mechanically deteriorated, those subjected to 3 shots experienced a complete failure at the end of the experiment. A numerical study was also conducted using an ABAQUS package program. While the adherends were modelled using the Johnson-Cook deformation parameters, an elastoplastic behavior of the adhesive was used as input data in the analyses. It seems the experimental results confirm the numerical ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ballistic%20tests" title="ballistic tests">ballistic tests</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesive%20joints" title=" adhesive joints"> adhesive joints</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SLJ" title=" SLJ"> SLJ</a> </p> <a href="https://publications.waset.org/abstracts/180863/effects-of-repeated-high-loadings-on-the-performance-of-adhesively-bonded-single-lap-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180863.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">64</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">34470</span> Numerical Modeling of Flow in USBR II Stilling Basin with End Adverse Slope</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Babaali">Hamidreza Babaali</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mojtahedi"> Alireza Mojtahedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Soori"> Nasim Soori</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Soori"> Saba Soori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydraulic jump is one of the effective ways of energy dissipation in stilling basins that the &lrm;energy is highly dissipated by jumping.

A comparison between two different solution methods (<em>g</em> and <em>k-method</em>) of ZAERO<sup>©</sup> is also done. It is seen that, <em>k-method</em> gives closer result than the other one.

Some of these parameters were obtained directly as a result of dynamic and quasi-static mechanical tests, and the remaining part was calibrated and determined by comparing numerical and experimental results. Woven glass/epoxy was used as the composite material and it was produced by vacuum infusion method. In the numerical model, composites are modeled as three-dimensional and layered.

The numerical investigation is based on the first and second order turbulence models. For the discretization of the equations system characterizing the flow, the finite volume method described by Patankar (1980) was used. The experimental study was conducted in order to evaluate dynamical characteristics of a heated axisymmetric air flow using the Laser Doppler Anemometer (LDA) which is a very accurate optical measurement method. Experimental and numerical results are compared and discussed.

Mechanical devices such as accelerometers are one of the sources of lack of quality in measuring modal testing parameters. In this paper, eliminating the accelerometer’s mass effect of the frequency response of the structure is studied. So, a strategy is used for eliminating the mass effect by using sensitivity analysis. In this method, the amount of mass change and the place to measure the structure’s response with least error in frequency correction is chosen. Experimental modal testing is carried out on a steel plate and the effect of accelerometer’s mass is omitted using this strategy. Finally, a good agreement is achieved between numerical and experimental results. <p class="card-text"><strong>Keywords:</strong> <a
