2-D Computational Analysis of a Vertical Axis Wind Turbine Airfoil

Akshay Basavaraj

This paper deals with the 2-D computational analysis of FX 66 S196 airfoil blade which is used in a Vertical Axis Wind Turbine (VAWT) [Ref.1]. The aerodynamic characteristics such as coefficient of lift and coefficient of drag are evaluated from 00 to 3600 using FLUENT 6.3.26. The geometry of the airfoil is developed in GAMBIT 2.4.6. The objective of this paper is to improve the efficiency of the VAWT airfoils at high angles of attack. Experimental results obtained from work done by Avin et al [Ref.4] are compared with for validity of the procedure used in FLUENT
