 ABSTRACT

In order to predict the local scour around the gravity platform, the paper simulated the flow field around the platform in two dimensional space with large eddy numerical simulation method and SIMPLEC pressure correction algorithm, which based on the finite volume method. Through the average flow field characteristics and integral parameters got, the basic characteristics of the wake structure could be understood.

Keywords: gravity platform; LES; SIMPLEC
