摘要
文中以某理想客滚船舱段模型为研究对象,基于VOF方法建立两相流体积模型,采用重叠网格和交界面网格技术,分析规则波下不同破口形状舱室模型破舱进水下的运动响应.结果表明:不同破口形状对破舱进水过程的影响主要表现为横摇时域的高频成分,且不同破口形状导致的流量不同.
Abstract
Based on VOF method,the volume model of two-phase flow was established with an ideal passenger ro-ro cabin model as the research object.By using overlapping grid and interface grid tech-nology,the motion response of cabin models with different breach shapes under regular waves was an-alyzed.The results show that the influence of different crevasse shapes on the water inflow process is mainly manifested in the high frequency component of rolling time domain,and the flow caused by dif-ferent crevasse shapes is different.
