Hybrid Numerical Simulation of Fluctuating Wind Field around a Wind Turbine Blade
College of Civil Engineering & Architecture, Zhejiang University, Hangzhou 310058, China |
Based on a hybrid numerical simulation method of the three-dimensional fluctuating wind field proposed before, the time-averaged turbulent flow field around a wind turbine blade was calculated by means of k-ε turbulence model. Reynolds stress tensors were calculated with the method recommended by ESDU and were used to modify the power spectral destiny functions of wind velocity. Three-dimensional fluctuating wind velocity field was simulated based on random flow generation method and provided a basis for the solution of the fluctuating wind load of wind turbine blades.
