摘　　要：本文基于Fluent软件,系统地介绍了对海洋工况下贮液设备进行数值模拟的相关步骤。在已有研究的基础上,研究了稳压器内液体在海洋一般振动工况下晃动的规律,提取了自由液面高度变化、内部压力波动和壁面压强变化,讨论了液体晃动对设备的影响以及海上小型堆的海洋环境设计基准,为后续研究提供借鉴,为反应堆系统的安全运行,对稳压器结构强度设计、其内部防晃液装置的优化及流固耦合分析等提供一定的理论基础。Based on the Fluent software, this paper systematically introduces the related steps of numerical simulation for liquid storage equipment under ocean conditions. On the basis of the existing research, the law of liquid sloshing in the general vibration condition of the pressurizer is studied. The change of the height of the free surface, the fluctuation of the internal pressure and the pressure change of the wall are extracted. The influence of the liquid sloshing on the equipment and the design datum of the ocean ring at sea are discussed, which provide the loan for the follow-up research. For the sale operation of the reactor system, it provides a theoretical basis for the structural strength design of the pressurizer, the optimization of its internal anti sloshing device and the fluid solid coupling analysis.
