CFD Analysis of Small Scale Wind Turbine Blade Under Low Reynolds Number

Abstract

The main aim of this project is to increase the lift force of the wind turbine blade with different airfoil profiles under low Reynolds number. This project describes the aerodynamic performance of wind turbine blade before and after modification of airfoils to increase the coefficient of lift of the horizontal axis wind turbine blade. In this study, a one meter long wind turbine blade suitable for 1.6 KW is designed standard and modified airfoils using SOLIDWORKS software. And Computational Fluid Dynamics analysis had done by using Software version (ANSYS WORKBENCH 16.2) to evaluate the performance between them at 15 m/s wind velocity. The outcome of the analysis study revealed that there was improvement in the coefficient of lift for the wind turbine blade with modification.
