Abstract
An icing phenomenon of wind turbine blade are caused by wind speed, air temperature, liquid water content, droplet size, and so on. In this study, the analyses were carried out at a liquid water content of 0.20g/㎥, droplet size of 25 um, wind speed of 11.4m/s and air temperatures of -15, -10, -5℃ using NREL 5MW wind turbine. The software uses FENSAP-ICE's CFD Flow Solver, Drop 3D and ICE 3D. The analysis of icing shape and mass with temperatures according to air foil was derived, and the required heat quantity for de-icing was calculated at NACA 64618 airfoil for air temperature of -15℃. Power curves with wind velocities are suggested for economical analysis.
