船舶在长峰不规则波中顶浪纵向运动的数值模拟

摘要

This paper based on in-depth study of the recent seakeeping research results and successfully construction the long-crested irregular wave tank by the CFD method.Choose the international towing tank conference(ITTC)recommended ship model DTMB 5512 as the experiment object,to simulate ship in long-crested irregular waves longitudinal motion numerically.the results compared with the potential flow theoretical calculation,the effect is good.%结合已有的耐波性研究成果,在基于粘性流理论,运用CFD方法成功构建长峰不规则波数值波浪水池的基础上,选择国际船模试验水池会议(ITTC)推荐瘦削型标准船模DTMB 5512作为试验对象,对船舶在长峰不规则波中纵向运动进行数值模拟,将数值模拟结果与势流理论计算结果进行比对,效果良好.
