Effect of Turbulence Model to Simulation Accuracy of Wind Turbine Blade

Abstract:

With the heightened concern for renewable energy because of significant energy problems, the interest on wind energy has been greatly increased. In this study, 4 kinds of RANS turbulence models were compared and discussed based on developed analysis model. At first, a numerical model for 1kW wind turbine blade was constructed. In the following step, Spalart-Allmaras, standard k-ε, RNG k-ε and Reynolds Stress turbulence models were candidated for comparison. The analysis results show that standard k-ε or RNG k-ε model is relatively good selection under the condition of considering accuracy and computational effort simultaneously. The developed analysis model and simulation results have made a theoretical basis for improving the simulation accuracy of wind turbine blade with minimum computational effort.
