基于不可压缩速度势理论，分析了旋转襟翼（在波能领域通常称为Oyster）潜入水中产生砰击的水动力问题。在时域内用边界元法求解。进行了两个典型案例研究。一个是襟翼落入平静的水中，另一个是落入来波中。模拟中考虑了襟翼下沉过程中形成的飞溅射流。当射流与主流相遇时，不考虑二次冲击，采用区域分解法处理，类似于复平面上的Riemann第二面的数学方法。在每个不重叠的子区域内求解问题，并在子区域的交界面上施加速度和压力连续条件。给出了襟翼以不同速度或加速度入水的详细结果。重力和波浪的影响也进行了研究。
The hydrodynamic problem of slamming generated by a rotating flap, commonly known as Oyster in the wave energy sector, plunging into water, is analysed based on the incompressible velocity potential theory. The problem is solved through the boundary element method in the time domain. Two typical case studies are undertaken. One is the flap plunging into calm water and the other into an incoming wave. The splash jet formed during the flap plunging is included in the simulation. When the jet meets the main flow, it is treated through the domain decomposition method without taking account the secondary impact, which is similar to the mathematical method of Riemann’s second sheet in the complex plane. The problem is solved in each non-overlapping subdomain, and the velocity and pressure continuity condition is imposed on the interface of the subdomains. Detailed results for the flap plunging into water with different velocities or accelerations are provided. The gravity and wave effects are also investigated.
