Influence of blade maximum thickness on airfoil performance with varied leading edge erosion rate

In this study, the effect of different blade shapes on aerodynamic performance NACA series airfoils under a wide variety working conditions at Reynolds number Re = 700,000 was explored. The SST k-ω turbulence model used for CFD method to investigate leading edge erosion airfoils. results indicated that an optimal thickness range exists considering erosion. If airfoil too thin or thick, increased, and significantly reduced. However, will not decrease greatly when moderate, even if increased. For same airfoil, less erosion, better its be. When degree (depth) small, variation size would affect airfoil. increases certain extent, decreases compared with original cases, but sensitivity change decreases.
