Surface Roughness Effects on Ice Shape of Wind Turbine

Abstract

Wind turbine blades icing often occurs in winter when the blades suffer from supercooled droplets. Ice on blades changes the airfoil profile, reducing the work efficiency of the wind turbine. In this paper, by establishing the icing model for wind turbine, the roughness effects on glaze ice growth are studied, where the ice shape is numerically simulated with different roughness.
