摘要
为研究海底地形尾流对潮流能水轮机水动力学性能的影响,采用CFD方法,使用开源软件Code_saturne,选取具有代表性的二维梯形地形,对有无地形两种工况下的水轮机的性能分别进行数值模拟,得到不同尖速比的水轮机性能参数曲线。通过水槽试验与数值模拟结果对比,验证用CFD数值模拟直接求解含有地形流场中的水轮机各项性能参数的可靠性。利用数值模拟方法对梯形地形的尾流分布进行分析,进而研究海底地形尾流对水轮机性能的影响距离,为潮流能水轮机的微观选址提供一定参考。
In order to do research on the effect of the terrain^s wake flow of seabed on the hydrodynamic performance of tidal current turbines, numerical simulation is conducted by using the Open Source CFD software Code saturne. By using this software, and under homogeneous geographical condition or the field with a trapezoidal terrain, the curves of turbine performance have been simulated with different tip speed ratios. The flume experiment results show that the simulation values are in agreement with the experimental values. Besides, the effectiveness of the tidal turbine simulation which is under a trapezoidal terrain by using the CFD method is proved by this experiment, which can further explore the influence distance of the terrain＇s wake flow. Therefore, this paper can provide some reference for the microscopic site choosing of the tidal current turbine.
