Abstract
Wind energy iscontributing to the majority of the energy production in the renewable energy sectors. Currently more research work is being carried out in the Vertical Axis Wind Turbine technology. It is a turbine in which the axis of rotation of rotor is perpendicular to the ground and also perpendicular to the wind direction. Literature is available for the wind blades which have the special curves such as NACA profile etc., the drawback of aerodynamics blades is themanufacturing difficulties due to the complex profile which leads to the high cost of blade manufacturing. The best choice of the profile to provide a better solution is flat rectangular blade. The dimensions of the rectangular blade are: blade height-176mm, rotor diameter-110mm, blade width-12mm, blade side width-4mm and has a cross section of 12*4mm This paper deals with the study on the effect of the rectangular flat plate under the high wind velocity. A 2D model was developed using Solid works software. CFD Analysis was performed to determine the wind velocity which gives a better performance. A Prototype was built to perform the experimental analysis, and to correlate the results obtained in the CFD analysis for validation and verification. The results show that the maximum coefficient performance of 0.3 is achieved with Tip Speed Ratio (TSR) ranging from 2 to 4. This study on the dynamics of the wind blade may lead to the advancement of the blade structure and thereby generating more power. This type of flat blade can be used in the heat recovery system in the industrial exhaust where high speed wind is available. The another new thing is discussed here using the IoT techniques to measure the torque for every azimuth angle in real time experiment.
