분사류에 의한 원통형 실린더 주위의 유동 해석

Abstract

The present study is aimed to analyze the multi-phase flow phenomena around a circular cylinder embedded in a sea of a few thousands meters depth. We use a standard RANS k-ε model with Launder and Spalding's wall function to describe the turbulent features of the flow. The governing equations are discretized using a FVM with a non-staggered grid applied to the momentum interpolation. A SIMPLEC elocity-pressure coupling method combined with SIP is adopted to solve the algebraic equation. As an intermediate stage of development, we validate the eveloped code on the single-phase flow around a circular cylinder. The computed results for circular cylinder are compared with experimental data. A preliminary computation of a single-phase injection flow through a cylindrical body is briefly presented. As a conclusion, the code developed in the present study has proved to be accurate, efficient and applicable to the injection flow through a cylindrical body immersed in deep sea water.
