In this paper, numerical simulations of de-icing with microwave heating power density for wind turbine blades in wind power generation are fully discussed using FLUENT. The ice melting model of wind turbine blade is established, and two operating conditions, with and without consideration of the incoming flow, are analyzed to determine the starting melting time of ice layers with different thicknesses, providing a basis for selecting the power density of microwave de-icing. The results indicate that with an increase in ice layer thickness and a decrease in ambient temperature, it is necessary to increase the input deicing power density to enhance de-icing efficiency. However, to balance energy consumption and economic feasibility, it is recommended to control the blade deicing power density below 4000W/m2.

摘要

In this paper, numerical simulations of de-icing with microwave heating power density for wind turbine blades in wind power generation are fully discussed using FLUENT. The ice melting model of wind turbine blade is established, and two operating conditions, with and without consideration of the incoming flow, are analyzed to determine the starting melting time of ice layers with different thicknesses, providing a basis for selecting the power density of microwave de-icing. The results indicate that with an increase in ice layer thickness and a decrease in ambient temperature, it is necessary to increase the input deicing power density to enhance de-icing efficiency. However, to balance energy consumption and economic feasibility, it is recommended to control the blade deicing power density below 4000W/m2.
