摘要

摘要: 应用三步有限元法结合大涡模拟方法(LES)离散非定常不可压流动的Navier-Stokes方程,模拟了波浪场中海底管线周围流场及其受力情况,并把数值模拟的结果与物理实验的实测结果进行了比较,两者符合较好。为了检验三维效应的影响,同时进行了二维和三维流场的数值模拟。

Abstract: A three-step finite element method (FEM) and a large eddy simulation (LES) are applied to incompressible turbulent flow around a seabed pipeline in relative high Reynolds number. Both two-dimensional and three-dimensional numerical simulations are carried out to determine the three-dimensional effect. The results of numerical simulation agree quite well with the wave forces acting on pipeline model measured in physical model test.
