Abstract

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.
