摘要
该文基于三维时域势流理论,对一种多浮摆式波浪能采能装置的水动力性能进行了时域模拟,获得了单浮摆及双浮摆系统的运动响应、浮摆所受波浪力矩及角速度。根据模拟参数,对单浮摆和多浮摆系统的水动力特性进行了比较。在此基础上,根据几何相似、运动相似等相似准则,进行了单、双浮摆系统的水力模型试验,获得了两种装置的波浪能采集效率。数值模拟及水力模型试验的结果表明,单浮摆的纵摇响应小于双浮摆的情况,浮摆间的相互作用可以提高波浪能的采能效率。
According to three-dimensional potential theory, the hydrodynamic characteristics in time-domain for a multi- pendulum wave power converter were simulated and the motion responses, the suffered wave torques and the angular velocities of pendulum were obtained for single-pendulum and double-pendulum systems respectively. Based on simulated parameters, the comparison in hydrodynamic characteristics between single-pendulum and double-pendulum systems was carried out. In addition, by geometric similarity and motion similarity criteria, the hydraulic model tests for two systems were conducted and the capture efficiencies to wave energy were obtained. The results from simulation and test show that the pitching RAOs of the single-pendulum is less than the double-pendulum system, and the interaction between pendulums can improve the capture efficiency of converter.
