Abstract Iced wind turbine often suffers from shutdown and security issues, which limits the development of wind power industry. A numerical study of droplet impingement on 3-D rotating blade was carried out by Lagrange method. The performance of droplets under various environmental and operating conditions was studied and verified in the artificial icing tests. Numerical results show that the collision region mainly accumulates at the leading edge and the tip of the blade, and the collision area also increases at the tip. Collision efficiency increases and collision area expands with the increase of media volume diameter. Lower rotating speed or higher wind speed will cause the collision region moving to pressure side of the blade. The numerical simulation shows good consistency with the icing test under rime ice condition.

Key words： Wind turbine icing 3-D numerical simulation droplet impingement characteristics Lagrange method icing test
