Date of Publication :7th August 2016

Abstract: Present paper reports, effect of turbulence model and wind velocity on aerodynamic performance of an airfoil, NERL S809. The computational simulations are done by using RANS steady equations. Among four turbulence model (standard k–?, Spalart–Allmaras, k–? and k–? SST) the best model has been selected on the basis of comparison with experimental results from available literature. The pressure coefficient, drag coefficient and lift coefficient are compared at different angle of attack, wind velocity using different solver. This computational simulation is carried out using Ansys-Fluent (14.0) software. The accurate aerodynamic load acting on blade of wind turbine is obtained by using, k–? SST turbulence model for unsteady flow behavior.
