摘要
关于发电涡轮在各种洋流速度和不同的桨距角度下所产生的拉力和功率。同时对旋转流场的流场机理进行了研究。使用根据三维粘性结构网格和非定常雷诺平均Navier-Stokes方程的CFD程序,在多重网格方法针对800毫米直径的洋流发电涡轮进行数值仿真,并与其实验模型在水洞和实验水槽中的实验结果加以比较,通过比较,数值仿真和实验结果比较吻合,同时数值仿真很好地反映了水洞和水槽实验的水动力特性,证明了开发的CFD计算方法同传统方法相比,能够完全满足后续洋流涡轮水动力设计上的要求,可为设计提供参考。
This paper presents the numerical predictions of 3 - D CFD rotor computations of an 800ram diameter model of marine current turbine （MCT）. In the paper CFD is applied to a rotor at stationary hydrodynamic conditions based on viscosity structural mesh, using the Reynolds Averaged Navier-Stokes （RANS） equations, Consequently, numerical predictions need to be verified. Simulations from the numerical prediction are compared with experimental measurements of the model of MCT which is experimented on in a cavitation tunnel and a towing tank. The experimental data includes measurements of power and thrust generated by the turbine for a series of blade pitch settings and speeds. The numerical predictions show similar results and provide a satisfactory representation of the experimental turbine performance. Such results provide confidence in using the CFD computation tools to develop the forthcoming design of marine current turbines.
