Design and Aerodynamic Analysis of Small HAWT Using a Novel Computational Approach

With the development of human living standard and rapid industrialisation, global consumption of electricity has increased many times. By proper planning, modelling, and design, effective utilisation of renewable energy can be achieved with the aim to fulfil electricity demand. In this context, wind energy is one of the most efficient clean energy that has potential to be the frontrunner. However, designing and control of wind energy system are somewhat difficult because of erratic nature of wind. This paper presents an analytic approach to design small horizontal axis wind turbine (HAWT) blade and investigate its characteristic. Computational code has been developed in MATLAB to find out the parameters of optimal blade shape of three-bladed wind turbine (WT). The performance of WT obtained analytically from this procedure is compared and verified with several other works reported earlier in various articles. The proposed design removes some of the lacuna existing in past works and improves the performance of WT system.
