Abstract The study investigates the influence of erosion over leading edge S809 series airfoil and its impact on aerodynamic performance wind turbine blades. research work determines how affects blades at an angle attack varying from 0° to 45° for fixed Reynolds number 2.1 x 10 5 . To analyse flow characteristics, average pressure acting around surface is scanned with aid 20 taps. time 10,000 s...
