Wind Turbine Simulation Based on CFD Optimization Algorithm

Abstract

Blade profile changes lift and drag on the surface. So it is necessary to measure the power change of the wind turbine in the cold area by simulating the icing process. Computational fluid dynamics is considered as an effective method to predict ice accumulation. In this paper, the formation process of glaze ice was simulated by heat and mass transfer balance. The numerical calculation of 3-d blades was optimized by node interpolation and time step. Results show that the collision coefficient and ice shape would be changed by increasing the number of grid nodes. Through multi-step time iteration, it is easier to get the biangular ice in line with the actual situation.
