In this paper, towards mitigating secondary flow losses, a design optimization workflow is implemented for the casing geometry of a 1.5 stage axial flow turbine that improves the turbine isentropic efficiency. The improved turbine is used in an open thermodynamic gas cycle with regeneration and cogeneration. Performance estimates are obtained by the commercial software Cycle – Tempo. Design and off design conditions are considered as well as variations in inlet air temperature. Reductions in both the natural gas specific fuel consumption and in CO<sub>2</sub> emissions are predicted by using the gas turbine cycle fitted with the new casing design. These gains are attractive towards enhancing the competitiveness and reducing the environmental impact of thermal power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20flow%20turbine" title="axial flow turbine">axial flow turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine%20power%20plant" title=" gas turbine power plant"> gas turbine power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/93179/improving-the-performance-of-gas-turbine-power-plant-by-modified-axial-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93179.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">161</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">12858</span> A Design Method for Wind Turbine Blade to Have Uniform Strength and Optimum Power Generation Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pengfei%20Liu">Pengfei Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yiyi%20Xu"> Yiyi Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There have been substantial incidents of wind turbine blade fractures and failures due to the lack of systematic blade strength design method incorporated with the aerodynamic forces and power generation efficiency. This research was to develop a methodology and procedure for the wind turbine rotor blade strength taking into account the strength, integration, and aerodynamic performance in terms of power generation efficiency. The wind turbine blade designed using this method and procedure will have a uniform strength across the span to save unnecessary thickness in many blade radial locations and yet to maintain the optimum power generation performance. A turbine rotor code, taking into account both aerodynamic and structural properties, was developed. An existing wind turbine blade was used as an example.

Since their high energy density per unit volume and low pollutant emissions, gas turbines are classified as clean energy. In order to obtain better performance, the turbine inlet temperature of the current gas turbine is operated at about 1600℃, and thermal damage is a very serious problem. Especially, these thermal damages are more prominent in off-design conditions than in design conditions. In this study, the thermal damage characteristics of high temperature components of a gas turbine made of a single crystal material are studied numerically for the off-design operating conditions. The target gas turbine is configured as a reheat cycle and is operated in peak load operation mode, not normal operation. In particular, the target gas turbine features a lot of low-load operation. In this study, a commercial code, ANSYS 18.2, was used for analyzing the thermal-flow coupling problems. As a result, the flow separation phenomenon on the pressure side due to the flow reduction was remarkable at the off-design condition, and the high heat transfer coefficient at the upper end of the suction surface due to the tip leakage flow was appeared. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title="gas turbine">gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20crystal%20blade" title=" single crystal blade"> single crystal blade</a>, <a href="https://publications.waset.org/abstracts/search?q=off-design" title=" off-design"> off-design</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20analysis" title=" thermal analysis"> thermal analysis</a> </p> <a href="https://publications.waset.org/abstracts/81581/analysis-of-thermal-damage-characteristics-of-high-pressure-turbine-blade-according-to-off-design-operating-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81581.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">213</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">12855</span> Environmental Life Cycle Assessment of Two Technologic Scenario of Wind Turbine Blades Composition for an Optimized Wind Turbine Design Using the Impact 2002+ Method and Using 15 Environmental Impact Indicators</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Jarrou">A.

This article aims to assess the environmental impacts associated with 1 kg of wind turbine blades. In order to carry out a realistic and precise study, the different stages of the life cycle of a wind turbine installation are included in the study (manufacture, installation, use, maintenance, dismantling, and waste treatment). The Impact 2002+ method used makes it possible to assess 15 impact indicators (human toxicity, terrestrial and aquatic ecotoxicity, climate change, land use, etc.).

Calculations have been made on the energy available in the wind and an energy analysis was then performed to see what wind speed is required for the system to work. The rotor has a radius of 0.53 m giving a swept area of 1.27 m2 and this gives a solidity of 0.5, which is the minimum theoretical optimum value for wind turbine. The average extracted torque of the wind turbine is 0.922 Nm and Tip speed ratio is one this shows, the tips are moving at equal the speed of the wind and by 2 rotating of blades. This is sufficient to sustain the desired flow rate of (0.3125X 10-3) m3 per second with a maximum head of 10m and the expected working is 4hr/day, and also overcome other barriers to motion such as friction. Based on this novel design, we are able to achieve a cost-effective solution and simultaneously effective in self-starting under low wind speeds and it can catch the wind from all directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Savonius%20wind%20turbine" title="Savonius wind turbine">Savonius wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=Small-scale%20irrigation" title=" Small-scale irrigation"> Small-scale irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=Vertical%20Axis%20Wind%20Turbine" title=" Vertical Axis Wind Turbine"> Vertical Axis Wind Turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=Water%20pump" title=" Water pump"> Water pump</a> </p> <a href="https://publications.waset.org/abstracts/121075/design-a-small-scale-irrigation-wind-powered-water-pump-using-a-savonius-type-vawt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121075.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">162</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">12853</span> Experimental Study of Near Wake of Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Rezaei">Ramin Rezaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Terry%20Ng"> Terry Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdollah%20Afjeh"> Abdollah Afjeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Near wake development of a wind turbine affects the aerodynamic loads on the tower and the wind turbine. Design considerations of both isolated wind turbines and wind farms must include unsteady wake flow conditions under which the turbines must operate. The consequent aerodynamic loads could lead to over design of wind turbines and adversely affect the cost of wind turbines and, in turn, the cost of energy produced by wind turbines. Reducing the weight of turbine rotors is particularly desirable since larger wind turbine rotors can be utilized without significantly increasing the cost of the supporting structure. Larger rotor diameters produce larger swept areas and consequently greater energy production from the wind thereby reducing the levelized cost of wind energy. To understand the development and structure of the near tower wake of a wind turbine, an experimental study was conducted to describe the flow field of the near wake for both upwind and downwind turbines. The study was conducted under controlled environment of a wind tunnel using a scaled model of a turbine. The NREL 5 MW reference wind turbine was used as a baseline design and was modified as necessary to design and build upwind and downwind scaled wind turbine models. This paper presents the results of the wind tunnel study using turbine models to quantify the near wake of upwind and downwind wind turbine configurations for various lengths of tower-to-turbine spacing. The variations of mean velocity and turbulence are measured using a computer-controlled, traversing hot wire probe. Additionally, smoke flow visualizations were conducted to qualitatively study the wake. The results show a more rapid dissipation of the near wake for an upwind configuration. The results can readily be incorporated into low fidelity system level turbine simulation tools to more accurately account for the wake on the aerodynamic loads of a upwind and downwind turbines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hot%20wire%20anemometry" title="hot wire anemometry">hot wire anemometry</a>, <a href="https://publications.waset.org/abstracts/search?q=near%20wake" title=" near wake"> near wake</a>, <a href="https://publications.waset.org/abstracts/search?q=upwind%20and%20downwind%20turbine.%20Hot%20wire%20anemometry" title=" upwind and downwind turbine.

A material has attributes: its density, it’s resistance, it’s cost, it’s resistance to corrosion. For the design of a product, a certain profile of these attributes is required: low density, resistance removed, low cost. The problem is then to identify this attribute profile and to compare it with those of the materials, in order to find the one that comes closest. The aim of this work is to demonstrate the feasibility of characterizing a mini turbine made of 3D printed fiber-filled composite material by the process of additive manufacturing, then compare the performance of the alloy turbine with the composite turbine according to the results of the simulation by Abaqus software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20materials" title=" composite materials"> composite materials</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20printer" title=" 3D printer"> 3D printer</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine" title=" turbine"> turbine</a> </p> <a href="https://publications.waset.org/abstracts/109739/integration-of-constraints-related-to-composite-materials-in-the-design-of-industrial-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109739.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">134</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">12847</span> Generative Design Method for Cooled Additively Manufactured Gas Turbine Parts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Wimmer">Thomas Wimmer</a>, <a href="https://publications.waset.org/abstracts/search?q=Bernhard%20Weigand"> Bernhard Weigand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The improvement of gas turbine efficiency is one of the main drivers of research and development in the gas turbine market. This has led to elevated gas turbine inlet temperatures beyond the melting point of the utilized materials. The turbine parts need to be actively cooled in order to withstand these harsh environments. However, the usage of compressor air as coolant decreases the overall gas turbine efficiency. Thus, coolant consumption needs to be minimized in order to gain the maximum advantage from higher turbine inlet temperatures. Therefore, sophisticated cooling designs for gas turbine parts aim to minimize coolant mass flow. New design space is accessible as additive manufacturing is maturing to industrial usage for the creation of hot gas flow path parts. By making use of this technology more efficient cooling schemes can be manufacture. In order to find such cooling schemes a generative design method is being developed. It generates cooling schemes randomly which adhere to a set of rules. These assure the sanity of the design. A huge amount of different cooling schemes are generated and implemented in a simulation environment where it is validated. Criteria for the fitness of the cooling schemes are coolant mass flow, maximum temperature and temperature gradients. This way the whole design space is sampled and a Pareto optimum front can be identified. This approach is applied to a flat plate, which resembles a simplified section of a hot gas flow path part. Realistic boundary conditions are applied and thermal barrier coating is accounted for in the simulation environment. The resulting cooling schemes are presented and compared to representative conventional cooling schemes. Further development of this method can give access to cooling schemes with an even better performance having higher complexity, which makes use of the available design space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title=" gas turbine"> gas turbine</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=heat%20transfer%20design" title=" heat transfer design"> heat transfer design</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/88494/generative-design-method-for-cooled-additively-manufactured-gas-turbine-parts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88494.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">12846</span> Experimental and CFD of Desgined Small Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarek%20A.%20Mekail">Tarek A.

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">12841</span> Numerical Study of 5kW Vertical Axis Wind Turbine Using DOE Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yan-Ting%20Lin">Yan-Ting Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Nian%20Su"> Wei-Nian Su</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to demonstrate the design of 5kW vertical axis wind turbine (VAWT) using DOE method.

In this aspect, wind energy is a very good option and there are two different wind turbines, horizontal axis wind turbine (HAWT) and vertical axis turbine (VAWT). For locations outside of integrated grid networks, vertical axis wind turbines (VAWT) present a feasible solution. However, those turbines have several drawbacks related to various setups, VAWT has a very low efficiency when compared with HAWT, but they work under different conditions and installation areas. This paper reviewed numerous measurements taken to improve the efficiency of VAWT configurations, either directly or indirectly related to the performance efficiency of the turbine. Additionally, the comparison and advantages of HAWT and VAWT turbines and also the findings of the design methodologies used for the VAWT design have been reviewed together with efficiency enhancement revision. Most of the newly modified designs are based on the turbine blade structure modification but need other studies on behalf other than electromechanical modification. Some of the techniques, like continuous variation of pitch angle control and swept area control, are not the most effective since VAWT is Omni-directional, and so wind direction is not a problem like HAWT. Hybrid system technology has become one of the most important and efficient methods to enhance the efficiency of VAWT. Besides hybridization, the contra-rotating method is also good if the installation area is big enough in an urban area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title="wind turbine">wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20axis%20wind%20turbine" title=" horizontal axis wind turbine"> horizontal axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20axis%20wind%20turbine" title=" vertical axis wind turbine"> vertical axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=hybridization" title=" hybridization"> hybridization</a> </p> <a href="https://publications.waset.org/abstracts/163049/review-of-vertical-axis-wind-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163049.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">101</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">12839</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.

To extract maximum annual energy product from an intermediately designed small wind turbine associated with measured wind data, numerous simulation is highly recommended to have a best fitting planform design with proper airfoil configuration. Since depending upon wind distribution with average wind speed, an optimal wind turbine planform design changes accordingly. It is theoretically not difficult, though, it is very inconveniently time-consuming design procedure to finalize conceptual layout of a desired small wind turbine. Thus, to help simulations easier and faster, a GUI software is developed to conveniently iterate and change airfoil types, wind data, and geometric blade data as well. With magnetic generator torque curve, peak power tracking simulation is also available to better match with the magnetic generator. Small wind turbine often lacks starting torque due to blade optimization. Thus this simulation is also embedded along with yaw design. This software provides various blade cross section details at user’s design convenience such as skin thickness control with fiber direction option, spar shape, and their material properties. Since small wind turbine is under international safety regulations with fatigue damage during normal operations and safety load analyses with ultimate excessive loads, load analyses are provided with each category mandated in the safety regulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GUI%20software" title="GUI software">GUI software</a>, <a href="https://publications.waset.org/abstracts/search?q=Low%20Reynold%E2%80%99s%20number%20aerodynamics" title=" Low Reynold’s number aerodynamics"> Low Reynold’s number aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20power%20tracking" title=" peak power tracking"> peak power tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20regulations" title=" safety regulations"> safety regulations</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine%20performance%20optimization" title=" wind turbine performance optimization"> wind turbine performance optimization</a> </p> <a href="https://publications.waset.org/abstracts/64036/software-development-for-both-small-wind-performance-optimization-and-structural-compliance-analysis-with-international-safety-regulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64036.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">304</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">12836</span> Effect of Thickness and Solidity on the Performance of Straight Type Vertical Axis Wind Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianyang%20Zhu">Jianyang Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lin%20Jiang"> Lin Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tixian%20Tian"> Tixian Tian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inspired by the increasing interesting on the wind power associated with production of clear electric power, a numerical experiment is applied to investigate the aerodynamic performance of straight type vertical axis wind turbine with different thickness and solidity, where the incompressible Navier-Stokes (N-S) equations coupled with dynamic mesh technique is solved. 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. In addition, delay stall and no interaction of the blade and previous separated vortex are observed around appropriate thickness and solidity turbine, therefore lead better performance characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20axis%20wind%20turbine" title="vertical axis wind turbine">vertical axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=N-S%20equations" title=" N-S equations"> N-S equations</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20mesh%20technique" title=" dynamic mesh technique"> dynamic mesh technique</a>, <a href="https://publications.waset.org/abstracts/search?q=thickness" title=" thickness"> thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=solidity" title=" solidity"> solidity</a> </p> <a href="https://publications.waset.org/abstracts/54216/effect-of-thickness-and-solidity-on-the-performance-of-straight-type-vertical-axis-wind-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54216.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">265</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">12835</span> An Investigation on Designing and Enhancing the Performance of H-Darrieus Wind Turbine of 10KW at the Medium Range of Wind Speed in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ich%20Long%20Ngo">Ich Long Ngo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinh%20Tai%20Dang"> Dinh Tai Dang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ngoc%20Tu%20Nguyen"> Ngoc Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Minh%20Duc%20Nguyen"> Minh Duc Nguyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes an investigation on designing and enhancing the performance of H-Darrieus wind turbine (HDWT) of 10kW at the medium wind speed. The aerodynamic characteristics of this turbine were investigated by both theoretical and numerical approaches. The optimal design procedure was first proposed to enhance the power coefficient under various effects, such as airfoil type, number of blades, solidity, aspect ratio, and tip speed ratio. As a result, the overall design of the 10kW HDWT was well achieved, and the power characteristic of this turbine was found by numerical approach. Additionally, the maximum power coefficient predicted is up to 0.41 at the tip speed ratio of 3.7 and wind speed of 8 m/s. Particularly, a generalized correlation of power coefficient with tip speed ratio and wind speed is first proposed. These results obtained are very useful for enhancing the performance of the HDWTs placed in a country with high wind power potential like Vietnam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20multiple%20stream%20tube" title=" double multiple stream tube"> double multiple stream tube</a>, <a href="https://publications.waset.org/abstracts/search?q=h-darrieus%20wind%20turbine" title=" h-darrieus wind turbine"> h-darrieus wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/163982/an-investigation-on-designing-and-enhancing-the-performance-of-h-darrieus-wind-turbine-of-10kw-at-the-medium-range-of-wind-speed-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163982.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">118</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">12834</span> The Effect of Velocity Increment by Blockage Factor on Savonius Hydrokinetic Turbine Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thochi%20Seb%20Rengma">Thochi Seb Rengma</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahendra%20Kumar%20Gupta"> Mahendra Kumar Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20M.%20V.%20Subbarao"> P.

The hydrokinetic turbine uses the kinetic energy of the water and maybe put it directly into the natural flow of water without dams. For off-grid power production, the Savonius-type vertical axis turbine is the easiest to design and manufacture. This proposal uses three-dimensional computational fluid dynamics (CFD) simulations to measure the considerable interaction and complexity of turbine blades. Savonius hydrokinetic turbine (SHKT) performance is affected by a blockage in the river, canals, and waterways. Putting a large object in a water channel causes water obstruction and raises local free stream velocity. The blockage correction factor or velocity increment measures the impact of velocity on the performance. SHKT performance is evaluated by comparing power coefficient (Cp) with tip-speed ratio (TSR) at various blockage ratios. The maximum Cp was obtained at a TSR of 1.1 with a blockage ratio of 45%, whereas TSR of 0.8 yielded the highest Cp without blockage. The greatest Cp of 0.29 was obtained with a 45% blockage ratio compared to a Cp max of 0.18 without a blockage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=savonius%20hydrokinetic%20turbine" title="savonius hydrokinetic turbine">savonius hydrokinetic turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=blockage%20ratio" title=" blockage ratio"> blockage ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20axis%20turbine" title=" vertical axis turbine"> vertical axis turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20coefficient" title=" power coefficient"> power coefficient</a> </p> <a href="https://publications.waset.org/abstracts/162783/the-effect-of-velocity-increment-by-blockage-factor-on-savonius-hydrokinetic-turbine-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162783.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">132</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">12833</span> Design Parameters Optimization of a Gas Turbine with Exhaust Gas Recirculation: An Energy and Exergy Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joe%20Hachem">Joe Hachem</a>, <a href="https://publications.waset.org/abstracts/search?q=Marianne%20Cuif-Sjostrand"> Marianne Cuif-Sjostrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Schuhler"> Thierry Schuhler</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Orhon"> Dominique Orhon</a>, <a href="https://publications.waset.org/abstracts/search?q=Assaad%20Zoughaib"> Assaad Zoughaib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exhaust gas recirculation, EGR, implementation on gas turbines is increasingly gaining the attention of many researchers. This emerging technology presents many advantages, such as lowering the NOx emissions and facilitating post-combustion carbon capture as the carbon dioxide concentration in the cycle increases. As interesting as this technology may seem, the gas turbine, or its thermodynamic equivalent, the Brayton cycle, shows an intrinsic efficiency decrease with increasing EGR rate. In this paper, a thermodynamic model is presented to show the cycle efficiency decrease with EGR, alternative values of design parameters of both the pressure ratio (PR) and the turbine inlet temperature (TIT) are then proposed to optimize the cycle efficiency with different EGR rates. Results show that depending on the given EGR rate, both the design PR & TIT should be increased to compensate for the deficit in efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbines" title="gas turbines">gas turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20gas%20recirculation" title=" exhaust gas recirculation"> exhaust gas recirculation</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20parameters%20optimization" title=" design parameters optimization"> design parameters optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20approach" title=" thermodynamic approach"> thermodynamic approach</a> </p> <a href="https://publications.waset.org/abstracts/135673/design-parameters-optimization-of-a-gas-turbine-with-exhaust-gas-recirculation-an-energy-and-exergy-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135673.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">145</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">12832</span> Off Design Modelling of 650MW Combined Cycle Gas Turbine Power Plant Integrated with a Retrofitted Inlet Fogging System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osarobo%20Omorogieva%20Ighodaro">Osarobo Omorogieva Ighodaro</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephus%20Otejere"> Josephus Otejere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper contains the modelling and simulation of GT13E2 combined cycle gas turbine with the aid of the software EBSILON PROFESSIONAL.

The validation results obtained ranged from -0.0038% to 0% in design condition while the results varied from -0.9202% to 10.24% The model shows that fogging decreases compressor inlet temperature which in turn decreases the power required to drive the compressor hence improving the simple cycle efficiency and hence increasing power generated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inlet%20fogging" title="inlet fogging">inlet fogging</a>, <a href="https://publications.waset.org/abstracts/search?q=off%20design" title=" off design"> off design</a>, <a href="https://publications.waset.org/abstracts/search?q=combined%20cycle" title=" combined cycle"> combined cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a> </p> <a href="https://publications.waset.org/abstracts/186927/off-design-modelling-of-650mw-combined-cycle-gas-turbine-power-plant-integrated-with-a-retrofitted-inlet-fogging-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186927.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">39</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">12831</span> Effect of Blade Shape on the Performance of Wells Turbine for Wave Energy Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katsuya%20Takasaki">Katsuya Takasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Manabu%20Takao"> Manabu Takao</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshiaki%20Setoguchi"> Toshiaki Setoguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of 3-dimensional (3D) blade on the turbine characteristics of Wells turbine for wave energy conversion has been investigated experimentally by model testing under steady flow conditions in the study, in order to improve the peak efficiency and the stall characteristics. 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. As a result, it was concluded that although the peak efficiency of Wells turbine can be improved by the use of the proposed 3D blade, its blade does not overcome the weakness of stalling. <p
