Numerical Study on Aerodynamic Performance of S809 Wind Turbine

Wind energy has emerged as one of the cleanest and sustainable sources of energy and is a potential resource for meeting the future’s electricity demand. Evaluating the aerodynamic performance of the turbine blade in complex environmental conditions is vital for designing and developing energy-efficient wind turbines. This work aims to undertake aerodynamic analysis of a Horizontal Axis Wind Turbine i.e. NREL Phase IV. Computational fluid dynamics (CFD) models are presented using ANSYS-CFX software. Blade geometries were tested at different wind speeds ranging from 5 m/s to 30 m/s. The power output and pressure coefficients obtained from numerical simulations are compared with experimental data published on wind turbine.
