초록

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.
