Numerical and experimental investigations of 14 different small wind turbine airfoils for 3 different reynolds number conditions

摘要

In this study, we have focused on commonly used 14 different small wind turbine airfoils (A18, BW3, Chic Y, E387, FX77, NACA 2414, RG 15, 5822, 5823, 56062, 57012, SD6060, SD7032, SD7062). The main purpose of the study is to determine the lift, drag and lift/drag coefficients of these airfoils with numerical analysis and to verify 2 best airfoil's results with experimental analysis. Airfoils were determined from past studies on small wind turbines. Numerical analyzes of the airfoils were done with Ansys Fluent fluid dynamics program. Experimental analyzes were done at wind tunnel in Erciyes University, Turkey. Lift and drag coefficients of these airfoils were determined for 50,000-100,000-200,000 Reynolds numbers.
