摘要
在海洋能源开发领域,潮流能作为一种新型的能源形式受到的关注。本文对船舶使用的柔性叶片潮流能发电系统中的水轮机进行深入研究,建立基本的海水流体力学模型。首先对常见水轮机的结构特点进行设计建模,然后从能量守恒的角度,对流体的湍流方程进行参数优化。通过数值演算和导数优化,得到叶轮受力分布与运动速率之间的关系,并得到仿真曲线。
In the field of ocean energy development, tidal current can be regarded as a new type of energy, and more attention is paid to it. In this paper, the turbine in tidal current power generation system of flexible blade is studied deeply.Then, the turbulence equation of the fluid is optimized by the energy conservation method. Through the numerical calculation and the derivative optimization, the force distribution and the velocity of the impeller are obtained. The numerical simulation of the hydrodynamic model is carried out. And the simulation curve is obtained.
