Aerodynamic analysis of Blade NACA 653-218 of Horizontal Axis Wind Turbine (HAWT) using Computational Fluid Dynamics

摘要

A Computational attempt to investigate the drag and liftforces which are the critical factor for an aerodynamic body atdifferent angle of attack (AOA) ranging from (-2° ??8°? and atReynolds number of the order of 3x106is made for a horizontal axiswind turbine blade. Airfoil NACA 65-218 with maximum thicknessof 18% at 39.9% chord length is selected for the purpose andsimulation is performed using Computational fluid Dynamics(CFD).The length of blade is taken as 37 meter which is standarddesigned blade of GE 1.5-77 1.5MW turbine.
