在船舶安全性研究过程中船舶破舱进水始终是重点关注的危险事件之一。本文通过建立船舶舱室底部破损的简化模型并使用流体力学计算软件Fluent，采用VOF法进行仿真计算。通过检测进水量得出基于瞬态的船舶破舱进水流量系数，并比较在底部破损口的情况下，不同破损大小、形状及破口所处水深对进水流量系数的影响，为船舶破舱事件中可以更加快速准确地评估船舶破损状况并选择合理救援救助方案提供参考。
Flooding is one of the most concerned critical events while researching marine safety. In this paper, a series of simplified models based on bottom damaged ship has been established and Ansys Fluent has been used to perform simulation calculations by taking VOF method. The result of calculations offered the transient-based coefficient of discharge. By comparing the differences between coefficient of discharge with different sizes、shapes and depths of bottom breach, it can offer a useful reference for crew to evaluate ship damage and help quicker solving problem.
