| 摘 要： | 本文基于致动线模型求解三维Navier-Stokes方程的方法,对NTNU的"BlindTest1"风力机尾流场进行了数值模拟。该方法避免了求解实际叶片的表面边界层,无需使用动网格,从而大大降低了网格量和计算时间,非常适用于尾流场的模拟。该文所有计算均基于OpenFOAM自定义的求解器ALMpisoFoam。推力和功率的计算值与实验值吻合得很好,验证了求解器的正确性。3个典型叶尖速比下的轴向诱导因子、湍动能和尾涡结构等也在文中进行了简要分析。

| Abstract: | This paper uses the "Blind test 1" experiment in NTNU as the set-up for the numerical simulations,and the actua tor line code to model the wind turbine.The actuator line method avoids fully resolving the blade geometry and using the moving mesh technique.So this method reduces significantly the amount of grids and computational time,and it is very suitable for the simulation of the turbine wakes.All simulations are based on ALMpisoFoam,a solver developed on OpenFOAM.The calculation values of thrust and power agree well with the experiment data.Some detailed results in three typical tip speed ratios such as the axial induced factor,turbulent energy and wake structure are also presented in this paper. |
