We came to an idea that Wells turbine can be used as power augmentation device in the crosswind something like sails of a yacht. Wells turbine always rotates in the same direction irrespective of the incoming flow direction, and we use it in the small-scale power generation in the ocean where waves create an oscillating flow. We incorporate the turbine to the wheel of a bike. A commercial device integrates strain gauges in the crank of a bike and transmitted force and torque applied to the pedal of the bike as an e-mail to the driver’s mobile phone. We can analyze the unsteady data in a spreadsheet sent from the crank sensor. We run the bike with the crank sensor on the rollers at the exit of a low-speed wind tunnel and analyze the effect of the crosswind to the wheel with a Wells turbine. We also test the aerodynamic characteristics of the turbine separately. Although power gain depends on the flow direction, several Watts increase might be possible by the Wells turbine incorporated to a bike wheel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=Wells%20turbine" title=" Wells turbine"> Wells turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=bicycle" title=" bicycle"> bicycle</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20engineering" title=" wind engineering"> wind engineering</a> </p> <a href="https://publications.waset.org/abstracts/84277/aerodynamic-bicycle-torque-augmentation-with-a-wells-turbine-in-wheels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84277.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">180</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">769</span> Mistuning in Radial Inflow Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valentina%20Futoryanova">Valentina Futoryanova</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugh%20Hunt"> Hugh Hunt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the common failure modes of the diesel engine turbochargers is high cycle fatigue of the turbine wheel blades. Mistuning of the blades due to the casting process is believed to contribute to the failure mode. Laser vibrometer is used to characterize mistuning for a population of turbine wheels through the analysis of the blade response to piezo speaker induced noise. The turbine wheel design under investigation is radial and is typically used in 6-12 L diesel engine applications. Amplitudes and resonance frequencies are reviewed and summarized. The study also includes test results for a paddle wheel that represents a perfectly tuned system and acts as a reference. Mass spring model is developed for the paddle wheel and the model suitability is tested against the actual data. Randomization is applied to the stiffness matrix to model the mistuning effect in the turbine wheels. Experimental data is shown to have good agreement with the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibration" title="vibration">vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=radial%20turbines" title=" radial turbines"> radial turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=mistuning" title=" mistuning"> mistuning</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20blades" title=" turbine blades"> turbine blades</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20analysis" title=" modal analysis"> modal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=periodic%20structures" title=" periodic structures"> periodic structures</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title=" finite element"> finite element</a> </p> <a href="https://publications.waset.org/abstracts/19840/mistuning-in-radial-inflow-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19840.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">432</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">768</span> Application of Powder Metallurgy Technologies for Gas Turbine Engine Wheel Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Liubov%20Magerramova">Liubov Magerramova</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Kratt"> Eugene Kratt</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Presniakov"> Pavel Presniakov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A detailed analysis has been performed for several schemes of Gas Turbine Wheels production based on additive and powder technologies including metal, ceramic, and stereolithography 3-D printing. During the process of development and debugging of gas turbine engine components, different versions of these components must be manufactured and tested. Cooled blades of the turbine are among of these components. They are usually produced by traditional casting methods. This method requires long and costly design and manufacture of casting molds. Moreover, traditional manufacturing methods limit the design possibilities of complex critical parts of engine, so capabilities of Powder Metallurgy Techniques (PMT) were analyzed to manufacture the turbine wheel with air-cooled blades. PMT dramatically reduce time needed for such production and allow creating new complex design solutions aimed at improving the technical characteristics of the engine: improving fuel efficiency and environmental performance, increasing reliability, and reducing weight. To accelerate and simplify the blades manufacturing process, several options based on additive technologies were used. The options were implemented in the form of various casting equipment for the manufacturing of blades. Methods of powder metallurgy were applied for connecting the blades with the disc. The optimal production scheme and a set of technologies for the manufacturing of blades and turbine wheel and other parts of the engine can be selected on the basis of the options considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20technologies" title="additive technologies">additive technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine%20engine" title=" gas turbine engine"> gas turbine engine</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20technology" title=" powder technology"> powder technology</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20wheel" title=" turbine wheel"> turbine wheel</a> </p> <a href="https://publications.waset.org/abstracts/66360/application-of-powder-metallurgy-technologies-for-gas-turbine-engine-wheel-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66360.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">320</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">767</span> Improving the Technology of Assembly by Use of Computer Calculations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariya%20V.%20Yanyukina">Mariya V.

However, the assembling accuracy depends not only on the quality of the production process but also on the correctness of the assembly process. Therefore, preliminary calculations of assembly stages are carried out to verify the correspondence of real geometric parameters to their acceptable values. In the aviation industry, most calculations involve interacting dimensional chains. This greatly complicates the task. Solving such problems requires a special approach. The purpose of this article is to carry out the problem of improving the technology of assembly of aviation units by use of computer calculations. One of the actual examples of the assembly unit, in which there is an interacting dimensional chain, is the turbine wheel of gas turbine engine. Dimensional chain of turbine wheel is formed by geometric parameters of disk and set of blades. The interaction of the dimensional chain consists in the formation of two chains. The first chain is formed by the dimensions that determine the location of the grooves for the installation of the blades, and the dimensions of the blade roots. The second dimensional chain is formed by the dimensions of the airfoil shroud platform. The interaction of the dimensional chain of the turbine wheel is the interdependence of the first and second chains by means of power circuits formed by a plurality of middle parts of the turbine blades. The timeliness of the calculation of the dimensional chain of the turbine wheel is the need to improve the technology of assembly of this unit. The task at hand contains geometric and mathematical components; therefore, its solution can be implemented following the algorithm: 1) research and analysis of production errors by geometric parameters; 2) development of a parametric model in the CAD system; 3) creation of set of CAD-models of details taking into account actual or generalized distributions of errors of geometrical parameters; 4) calculation model in the CAE-system, loading of various combinations of models of parts; 5) the accumulation of statistics and analysis. The main task is to pre-simulate the assembly process by calculating the interacting dimensional chains. The article describes the approach to the solution from the point of view of mathematical statistics, implemented in the software package Matlab. Within the framework of the study, there are data on the measurement of the components of the turbine wheel-blades and disks, as a result of which it is expected that the assembly process of the unit will be optimized by solving dimensional chains. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=assembly" title=" assembly"> assembly</a>, <a href="https://publications.waset.org/abstracts/search?q=interacting%20dimension%20chains" title=" interacting dimension chains"> interacting dimension chains</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine" title=" turbine"> turbine</a> </p> <a href="https://publications.waset.org/abstracts/71448/improving-the-technology-of-assembly-by-use-of-computer-calculations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71448.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">373</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">766</span> Study Variation of Blade Angle on the Performance of the Undershot Waterwheel on the Pico Scale</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Warjito">Warjito</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Geraldo"> Kevin Geraldo</a>, <a href="https://publications.waset.org/abstracts/search?q=Budiarso"> Budiarso</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Mizan"> Muhammad Mizan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafi%20Adhi%20Pranata"> Rafi Adhi Pranata</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Rizqi%20Syahnakri"> Farhan Rizqi Syahnakri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to data from 2021, the number of households in Indonesia that have access to on-grid electricity is claimed to have reached 99.28%, which means that around 0.7% of Indonesia's population (1.95 million people) still have no proper access to electricity and 38.1% of it comes from remote areas in Nusa Tenggara Timur. Remote areas are classified as areas with a small population of 30 to 60 families, have limited infrastructure, have scarce access to electricity and clean water, have a relatively weak economy, are behind in access to technological innovation, and earn a living mostly as farmers or fishermen. These people still need electricity but can’t afford the high cost of electricity from national on-grid sources. To overcome this, it is proposed that a hydroelectric power plant driven by a pico-hydro turbine with an undershot water wheel will be a suitable pico-hydro turbine technology because of the design, materials and installation of the turbine that is believed to be easier (i.e., operational and maintenance) and cheaper (i.e., investment and operating costs) than any other type. The comparative study of the angle of the undershot water wheel blades will be discussed comprehensively. This study will look into the best variation of curved blades on an undershot water wheel that produces maximum hydraulic efficiency. In this study, the blade angles were varied by 180 ̊, 160 ̊, and 140 ̊. Two methods of analysis will be used, which are analytical and numerical methods. The analytical method will be based on calculations of the amount of torque and rotational speed of the turbine, which is used to obtain the input and output power of the turbine. Whereas the numerical method will use the ANSYS application to simulate the flow during the collision with the designed turbine blades. It can be concluded, based on the analytical and numerical methods, that the best angle for the blade is 140 ̊, with an efficiency of 43.52% for the analytical method and 37.15% for the numerical method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pico%20hydro" title="pico hydro">pico hydro</a>, <a href="https://publications.waset.org/abstracts/search?q=undershot%20waterwheel" title=" undershot waterwheel"> undershot waterwheel</a>, <a href="https://publications.waset.org/abstracts/search?q=blade%20angle" title=" blade angle"> blade angle</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a> </p> <a href="https://publications.waset.org/abstracts/167638/study-variation-of-blade-angle-on-the-performance-of-the-undershot-waterwheel-on-the-pico-scale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167638.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">77</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">765</span> The Effect of Surface Conditions on Wear of a Railway Wheel and Rail</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Shebani">A.

Twin disc wear testing is used extensively for studying wear of wheel and rail materials. The University of Huddersfield twin disc rig was used in this paper to examine the effect of surface conditions on wheel and rail wear measurement under a range of wheel/rail contact conditions, with and without contaminants. This work focuses on an investigation of the effect of dry, wet, and lubricated conditions and the effect of contaminants such as sand on wheel and rail wear. The wheel and rail wear measurements were carried out by using a replica material and an optical profilometer that allows measurement of wear in difficult location with high accuracy. The results have demonstrated the rate at which both water and oil reduce wheel and rail wear. Scratches and other damage were seen on the wheel and rail surfaces after the addition of sand and consequently both wheel and rail wear damage rates increased under these conditions. This work introduced the replica material and an optical instrument as effective tools to study the effect of surface conditions on wheel and rail wear. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=railway%20wheel%2Frail%20wear" title="railway wheel/rail wear">railway wheel/rail wear</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20conditions" title=" surface conditions"> surface conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=twin%20disc%20test%20rig" title=" twin disc test rig"> twin disc test rig</a>, <a href="https://publications.waset.org/abstracts/search?q=replica%20material" title=" replica material"> replica material</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicona%20profilometer" title=" Alicona profilometer"> Alicona profilometer</a> </p> <a href="https://publications.waset.org/abstracts/47795/the-effect-of-surface-conditions-on-wear-of-a-railway-wheel-and-rail" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47795.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">352</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">764</span> Dynamic Stability Assessment of Different Wheel Sized Bicycles Based on Current Frame Design Practice with ISO Requirement for Bicycle Safety </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Milan%20Paudel">Milan Paudel</a>, <a href="https://publications.waset.org/abstracts/search?q=Fook%20Fah%20Yap"> Fook Fah Yap</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20K.%20Bastola"> Anil K.

Although small wheel bicycles are designed using the similar approach and guidelines that have worked well for big wheel bicycles, the performance of the big wheelers and the smaller wheelers are markedly different. Since both the big wheelers and small wheelers have same fundamental geometry, most blame the small wheel for this discrepancy in the performance. This paper reviews existing guidelines for bicycle design, especially the front steering geometry for the bicycle, and provides a systematic and quantitative analysis of different wheel sized bicycles. A validated mathematical model has been used as a tool to assess the dynamic performance of the bicycles in term of their self-stability. The results obtained were found to corroborate the subjective perception of cyclists for small wheel bicycles. The current approach for small wheel bicycle design requires higher speed to be self-stable. However, it was found that increasing the headtube angle and selecting a proper trail could improve the dynamic performance of small wheel bicycles. A range of parameters for front steering geometry has been identified for small wheel bicycles that have comparable stability as big wheel bicycles. Interestingly, most of the identified geometries are found to be beyond the ISO recommended range and seem to counter the current approach of small wheel bicycle design. Therefore, it was successfully shown that the guidelines for big wheelers do not translate directly to small wheelers, but careful selection of the front geometry could make small wheel bicycles as stable as big wheel bicycles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20wheel%20bicycle" title="big wheel bicycle">big wheel bicycle</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20approach" title=" design approach"> design approach</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%20requirements" title=" ISO requirements"> ISO requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20wheel%20bicycle" title=" small wheel bicycle"> small wheel bicycle</a>, <a href="https://publications.waset.org/abstracts/search?q=stability%20and%20performance" title=" stability and performance"> stability and performance</a> </p> <a href="https://publications.waset.org/abstracts/86408/dynamic-stability-assessment-of-different-wheel-sized-bicycles-based-on-current-frame-design-practice-with-iso-requirement-for-bicycle-safety" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86408.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">194</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">763</span> Dynamic Analysis of Turbine Foundation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mogens%20Saberi">Mogens Saberi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents different design approaches for the design of turbine foundations.

A turbine foundation is an important part of a power plant since a non-optimal behavior of the foundation can damage the turbine itself and thereby stop the power production with large consequences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20turbine%20design" title="dynamic turbine design">dynamic turbine design</a>, <a href="https://publications.waset.org/abstracts/search?q=harmonic%20response%20analysis" title=" harmonic response analysis"> harmonic response analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=practical%20turbine%20design%20experience" title=" practical turbine design experience"> practical turbine design experience</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20foundation" title=" concrete foundation"> concrete foundation</a> </p> <a href="https://publications.waset.org/abstracts/52233/dynamic-analysis-of-turbine-foundation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52233.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">316</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">762</span> Impact of Wheel-Housing on Aerodynamic Drag and Effect on Energy Consumption on an Bus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amitabh%20Das">Amitabh Das</a>, <a href="https://publications.waset.org/abstracts/search?q=Yash%20Jain"> Yash Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rafiq%20B.%20Agrewale"> Mohammad Rafiq B.

This paper deals with the CFD simulation of the flow around the wheels of a bus with different wheel housing geometry and pattern. Based on benchmarking a model of a bus is selected and analysis is performed. The aerodynamic drag coefficient is obtained and turbulence around wheels is observed using ANSYS Fluent CFD simulation for different combinations of wheel-housing at the front wheels, at the rear wheels and both in the front and rear wheels. The drag force is recorded and corresponding influence on energy consumption on an electric bus is evaluated mathematically. A comparison is drawn between energy consumption of bus body without wheel housing and bus body with wheel housing. The result shows a significant reduction in drag coefficient and fuel consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheel-housing" title="wheel-housing">wheel-housing</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20simulation" title=" CFD simulation"> CFD simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=drag%20coefficient" title=" drag coefficient"> drag coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption "> energy consumption </a> </p> <a href="https://publications.waset.org/abstracts/108694/impact-of-wheel-housing-on-aerodynamic-drag-and-effect-on-energy-consumption-on-an-bus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108694.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">185</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">761</span> Review of Modern Gas turbine Blade Cooling Technologies used in Aircraft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arun%20Prasath%20Subramanian">Arun Prasath Subramanian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The turbine Inlet Temperature is an important parameter which determines the efficiency of a gas turbine engine.

The soil draught was electronically measured using an on-the-go soil draught measuring instrumentation system developed for the purpose of this research. The results showed an exponential relationship between forward speed and draught, in which draught ranging between 24.91 and 744.44N increased with an increase in forward speed in the rigid wheel experiment. This is contrary to the polynomial relationship observed in the pneumatic wheel experiment in which the draught varied between 96.09 and 343.53 N. It was observed in the experiments that the optimum speed of 1.5 km/h had the least values of draught in both the pneumatic wheel and rigid wheel experiments, with higher values in the pneumatic experiment. It was generally noted that the rigid wheel planter with less value of draught requires less energy required for operation. It is therefore concluded that operating the semi-automatic cassava planter with rigid wheels will be more economical for cassava farmers than operating the planter with pneumatic wheels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cassava%20planter" title="Cassava planter">Cassava planter</a>, <a href="https://publications.waset.org/abstracts/search?q=planting" title=" planting"> planting</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20speed" title=" forward speed"> forward speed</a>, <a href="https://publications.waset.org/abstracts/search?q=draught" title=" draught"> draught</a>, <a href="https://publications.waset.org/abstracts/search?q=wheel%20type" title=" wheel type"> wheel type</a> </p> <a href="https://publications.waset.org/abstracts/156326/forward-speed-and-draught-requirement-of-a-semi-automatic-cassava-planter-under-different-wheel-usage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156326.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">96</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">759</span> Power Generation from Sewage by a Micro-Hydraulic Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomomi%20Uchiyama">Tomomi Uchiyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomoko%20Okayama"> Tomoko Okayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yukio%20Ide"> Yukio Ide</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is concerned with the development of a micro-hydraulic turbine for power generation installed in sewer pipes.

In order to accomplish such tasks, it is critical that the motion control functions without wheel slip and odometry error during the navigation of the two-wheeled mobile robot (WMR). Wheel slip and odometry error are disrupting factors on overall WMR performance in the form of deviation from desired trajectory, navigation, travel time and budgeted energy consumption. The wheeled mobile robot’s ability to operate at peak performance on various work surfaces without wheel slippage and odometry error is directly connected to four main parameters, which are the range of payload distribution, speed, wheel diameter, and wheel width. This paper analyses the effects of those parameters on overall performance and is concerned with determining the ideal range of parameters for optimum performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wheeled%20mobile%20robot" title="wheeled mobile robot">wheeled mobile robot</a>, <a href="https://publications.waset.org/abstracts/search?q=terrain" title=" terrain"> terrain</a>, <a href="https://publications.waset.org/abstracts/search?q=wheel%20slippage" title=" wheel slippage"> wheel slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=odometryerror" title=" odometryerror"> odometryerror</a>, <a href="https://publications.waset.org/abstracts/search?q=trajectory" title=" trajectory"> trajectory</a> </p> <a href="https://publications.waset.org/abstracts/38028/studies-on-affecting-factors-of-wheel-slip-and-odometry-error-on-real-time-of-wheeled-mobile-robots-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38028.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">284</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">754</span> Exergy Analysis of Regenerative Organic Rankine Cycle Using Turbine Bleeding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyoung%20Hoon%20Kim">Kyoung Hoon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents an exergetical performance analysis of regenerative organic Rankine cycle (ORC) using turbine bleeding based on the second law of thermodynamics for recovery of finite thermal energy.

This research concluded that by using structural steel, the efficiency of engine is improved and by increasing number of turbine blades, more waste heat from combustion chamber is emitted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turbocharger" title="turbocharger">turbocharger</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20blades" title=" turbine blades"> turbine blades</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20steel" title=" structural steel"> structural steel</a>, <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title=" ANSYS"> ANSYS</a> </p> <a href="https://publications.waset.org/abstracts/97552/stress-analysis-of-turbine-blades-of-turbocharger-using-structural-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97552.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">244</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">751</span> Study of Effect of Steering Column Orientation and Operator Platform Position on the Hand Vibration in Compactors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunil%20Bandaru">Sunil Bandaru</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Yv"> Suresh Yv</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivas%20Vanapalli"> Srinivas Vanapalli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy machinery especially compactors has more vibrations induced from the compactor mechanism than the engines. Since the operator’s comfort is most important in any of the machines, this paper shows interest in studying the vibrations on the steering wheel for a double drum compactor. As there are no standard procedures available for testing vibrations on the steering wheel of double drum compactors, this paper tries to evaluate the vibrations on the steering wheel by considering most of the possibilities. In addition to the feasibility for the operator to adjust the steering wheel tilt as in the case of automotive, there is an option for the operator to change the orientation of the operator platform for the complete view of the road’s edge on both the ends of the front and rear drums. When the orientation is either +/-180°, the operator will be closer to the compactor mechanism; also there is a possibility for the shuffle in the modes with respect to the operator. Hence it is mandatory to evaluate the vibrations levels in both cases. This paper attempts to evaluate the vibrations on the steering wheel by considering the two operator platform positions and three steering wheel tilting angles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEA" title="FEA">FEA</a>, <a href="https://publications.waset.org/abstracts/search?q=CAE" title=" CAE"> CAE</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20column" title=" steering column"> steering column</a>, <a href="https://publications.waset.org/abstracts/search?q=steering%20column%20orientation%20position" title=" steering column orientation position"> steering column orientation position</a> </p> <a href="https://publications.waset.org/abstracts/139895/study-of-effect-of-steering-column-orientation-and-operator-platform-position-on-the-hand-vibration-in-compactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139895.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">750</span> Modeling of a Vehicle Wheel System having a Built-in Suspension Structure Consisted of Radially Deployed Colloidal Spokes between Hub and Rim</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barenten%20Suciu">Barenten Suciu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, by replacing the traditional solid spokes with colloidal spokes, a vehicle wheel with a built-in suspension structure is proposed.

By analyzing the flow field, as well as energy coefficient of different thickness and solidity turbine, it is found that the thickness and solidity can significantly influence the performance of vertical axis wind turbine. For the turbine under low tip speed, the mean energy coefficient increase with the increasing of thickness and solidity, which may improve the self starting performance of the turbine. However for the turbine under high tip speed, the appropriate thickness and smaller solidity turbine possesses better performance.

The aim of the use of 3D blade is to prevent flow separation on the suction surface near the tip. The chord length is constant with radius and the blade profile changes gradually from mean radius to tip. The proposed blade profiles in the study are NACA0015 from hub to mean radius and NACA0025 at the tip. The performances of Wells turbine with 3D blades has been compared with those of the original Wells turbine, i.e. the turbine with 2-dimensional (2D) blades.

When the wheel is set in motion, following Faraday's Law, the movement of the magnet within the coil induces an electric current. The paper includes an experiment to measure the output voltage of electromagnetics, as well as a numerical simulation to further explore the potential of this energy harvesting approach.

A telematics device contains a GPS module for tracking and a 3-axis accelerometer for shock detection. Besides these basic functions, it is desired to use the integrated accelerometer for condition monitoring without any additional sensors. Wheel flats as a common type of failure on wheel tread cause large impacts on wagons and infrastructure as well as impulsive noise. A large wheel flat may even cause safety issues such as derailments. In this sense, this paper proposes a machine learning approach for wheel flat detection by using car body accelerations. Due to suspension systems, impulsive signals caused by wheel flats are damped significantly and thus could be buried in signal noise and disturbances. Therefore, it is very challenging to detect wheel flats using car body accelerations. The proposed algorithm considers the envelope spectrum of car body accelerations to eliminate the effect of noise and disturbances. Subsequently, a 1-D convolutional neural network (CNN), which is well known as a deep learning method, is constructed to automatically extract features in the envelope-frequency domain and conduct classification. The constructed CNN is trained and tested on field test data, which are measured on the underframe of a tank wagon with a wheel flat of 20 mm length in the operational condition. The test results demonstrate the good performance of the proposed algorithm for real-time fault detection. <p class="card-text"><strong>Keywords:</strong> <a
