海洋油气开采的过程中,油气在海底通过海底管线进行运输。当雷诺数改变时,海底管线周围的流场也会相应发生改变,因此研究管线周围流场分布对分析管线受力情况至关重要。本文研究了海底管道在层流和紊流的情况下,不同流速,不同的床面粗糙度以及不同位置海底管线等情况进行了建模和分析,绘制了不同情况下流场分布图。计算结果表明:(1)同一位置,不同流速下,海流绕流管线形成的流场不同,当流速超过某一限定值后,会出现涡流。(2)不同位置,相同速度下,海流绕流管线形成的流场有所不同。通过数值模拟,对不同情况下的管线受力情况有了清晰的认识,对工程实际操作可以起到指导作用。 关键词:海底管线;海流力;流型;数值模拟;

This work describes a way to apply 3D Finite Element Analysis (FEA) to the thermal design of power electronic modules using simplified geometry models of the system components. The method here presented can overcome the problem of solving equation systems with a very high number of Degrees Of Freedom (DOF) due to complex geometry of a power module.
