摘　　要：波浪中船舶破损进水流动现象受破舱形状、波浪等因素的影响,具有强非线性水动力特征.为了提高数值预报精度和深入理解力学机理,需要多种形式的动态场景数据和相关物理量的实时数据.计算流体力学方法是破舱进水动态演变过程仿真的有效工具.论文综述计算流体力学方法在破舱稳性时域仿真中应用的进展,分析了方法的局限性和优点,并总结和展望了这种仿真技术在破舱稳性时域预报中的前景.Flooding phenomenon on a damaged ship in waves is complicated,and the flooding process is highly non-linear due to several effects like damage opening,and waves.In order to improve the accuracy of numerical prediction and understand the physical mechanism,various forms of hydrodynamic flooding scenario and real-time data of related flow parameters are needed.Today CFD method has become an effective tool to simulate the dynamic evolutionary process of damaged ship's flooding.In this paper an overview of CFD method for the time domain simulation of damaged stability is presented,as well as the strength and limitation of the method are analyzed.A summary and outlook of the method for prediction of damaged stability in the time domain are provided.
