| 目的 带坞舱船舶尾部具有与外界连通的自由液面，由于船舶运动会在坞舱内产生波浪，形成有害的波浪砰击，影响舱内装备的正常作业。针对这一问题，系统地对带坞舱船舶尾舱内的消浪方案进行模拟与优化，提出一套具有良好消浪性能的消浪装置方案。方法 以荷兰皇家海军两栖运输船为目标进行三维建模，使用CFD方法对其进行不同波浪下船舶响应模拟和分析，监测船舶的运动响应和舱内多个监测点的波高情况，使用多孔挡板为基础，给出一套消浪装置，并进行带有消浪装置方案的船舶响应模拟，评估该消浪装置方案的消浪性能。结果 对舱内首端和侧壁布置多孔板消浪装置，消浪效果可达40%~50%，验证了该消浪装置的可行性。结论 采用多孔介质区域模型对带有多孔介质消浪装置的整船进行数值模拟，在计算效率远高于对实际物理模型建模的同时，可以得到较好的消浪效果。 |

| The tail of a ship with a dock cabin has a free surface that is connected to the outside. Due to the motion of the ship, waves can be generated inside the dock cabin, causing harmful wave slamming and affecting the normal operation of equipment inside the cabin. To address this issue, the work aims to propose a wave dissipation device scheme with good wave dissipation performance by systematically simulating and optimizing the wave dissipation scheme in the tail tank of ships with dock cabins. With the amphibious transport ship of the Royal Netherlands Navy as the target, 3D modeling was carried out, and the ship response under different waves was simulated and analyzed by CFD method. The motion response of the ship and the wave height of multiple monitoring points in the cabin were monitored. Based on the use of porous baffles, a set of wave dissipation device was given, and the response simulation of the ship with wave dissipation device scheme was carried out to evaluate the wave dissipation performance of the scheme. The installation of porous baffle wave dissipating devices on the front and side walls of the cabin could achieve a wave dissipation effect of up to 40%~50%, verifying the feasibility of this wave dissipation device. The porous medium area model is used to simulate the whole ship with porous medium wave dissipation device. The calculation efficiency is much higher than that of the actual physical model modeling, and the wave dissipation effect is better. |
