Numerical simulation of unsteady aerodynamic characteristics of wind turbine rotational blade
摘要
Abstract
Based on computational fluid dynamics (CFD) method,this paper simulated the aerodynamic characteristics of NREL Phase VI wind turbine.Reynolds-Averaged Navier-Stokes (URANS) turbulence models are used in the simulations,and extensive comparisons with experimental data are performed.By the comparison for power,thrust and sectional force coefficients of NREL Phase Ⅵ wind turbine between CFD and NREL,the results at constant pitch and variable wind speed show that the CFD predictions match the experimental data consistently well at low wind speed.At high wind speed,there is a little difference due to the effects of flow separation.The simulation results reveal the unsteady aerodynamic characteristics of wind turbine blade with three-dimensional rotational effect.关键词
