摘要

本文通过数值模拟研究了一种新型潮汐能水轮机的运动和水动力性能。通过动网格法,得到了叶片的开合顺序和转子的运动,得到了不同叶尖速比下的角速度和平均能量利用系数。通过对不同叶尖速比下水轮机输出功率和能量利用系数的积分,确定了最佳叶尖速比,为水轮机原型设计提供了数据支持。

Numerical simulation of hydrodynamic performance of blade position-variable hydraulic turbine

This paper presents a study of the movement and the hydrodynamic performance of a new tide-powered hydraulic turbine through numerical simulations. By means of the moving mesh method, the open-closed sequences of the blades and the movement of the rotors are obtained and the angular velocity and the average energy utilization coefficient under different tip speed ratios are also obtained. Moreover, the optimum tip speed ratio is identified by integrating the output power and the energy utilization coefficient of the hydraulic turbine with different tip speed ratios, providing data support for the prototype design of the hydraulic turbine.
