摘要：

为了预测串列布置双转子海流机(MCT)的水动力性能,采用大涡模拟(LES)和Spalart-Allmaras(SA)单方程湍流模型对单转子海流机在设计工况下的流场进行模拟,分析单转子海流机的水动力性能,与实验结果进行对比验证.结果表明,LES大涡模拟和SA模型都能较好地预测海流机的水动力性能.采用LES方法研究串列布置双转子海流机的水动力性能,获得转子间距对海流机性能的影响规律.结果表明,对于该海流机,在5倍叶轮直径的间距内,处于下游海流机的性能受到较大影响,要保证串列布置的双转子海流机的输出性能,间距须达到30倍的叶轮直径.
Abstract:

The flow field of a marine current turbine (MCT) with single rotor was simulated based on large eddy simulation (LES) and Spalart-Allmaras (SA) turbulence model in order to predict the hydrodynamic performance of MCT with dual rotor. The performance of the MCT was obtained and compared with the experimental results. Results show that both SA model and LES model can well predict hydrodynamic performance. The flow field of MCT with dual rotor in tandem arrangement was simulated with LES model. The influence of the distance between two rotors on the performance of the MCT was analyzed. Results show that the performance of downstream rotor is greatly affected when the distance between two rotors is less than 5 times of rotor diameter. In order to keep a high performance for the MCT, the distance should be over 30 times of rotor diameter.
