Experimental study on aerodynamic performance of FFA-W3-270 airfoil for axial wind turbine blade

Abstract

The experimental tests are particularly important to achieve the high accuracy results for fluid flow around bodies and exact prediction of aerodynamics characteristics in industrial applications. Additionally the experimental results could be a credit yardstick to the validation of numerical results. In this study, we focus on the experimental investigation to analyse the aerodynamic characteristic of FFA-W3-270 airfoil. The airfoil shape has been adopted according to report for FFA airfoils series. The experiments were conducted at the Universiti Teknologi Malaysia Low Speed Wind Tunnel (UTM-LST). The experiments are accomplished to obtain lift, drag and moment coefficients and pressure distribution under various angles of attacks and the chord flow Reynolds number of 5×105 and 1×106.
