| 摘 要： | 为研究水平轴潮流能发电装置结构对其水动力性能的影响,运用格子玻尔兹曼(LBM)方法,建立水平轴潮流能发电装置的数值模拟分析模型,对水轮机在不同尖速比工况下的水动力性能进行模拟。将模拟结果与同工况水池拖曳实验得到的数据相对比,二者捕获能系数误差在2%左右,验证了LBM方法的可行性和准确性。在此基础上利用LBM方法研究机舱和立柱结构对水轮机特性的影响,得到其对水轮机捕获效率的影响规律。

| Abstract: | In order to give out the effect of structure on the horizontal axis tidal hydrodynamic performance device, Lattice Boltzmann (LBM) method was used to establish the numerical simulation model of the horizontal axis tidal current energy generator, and the hydrodynamic performance of the turbine under different tip speed ratio conditions was simulated. The simulation results were compared with the data obtained from the towing experiment in the same working condition, and the results show that the error of the acquisition energy coefficient is about 2 %.The feasibility and accuracy of the LBM method were verified. The influence of the structure of engine room and column on the characteristics of hydraulic turbine was studied by LBM method, and the influence of the structure on the efficiency of the turbine was obtained. |
