선박 운동과 내부 유동의 연성 운동에 관한 수치해석 연구

Abstract

This paper presents a numerical method to solve the ship motion with internal fluid. Physically the internal fluid is coupled with the ship motion. Hitherto the numerical results of the coupled motion predict the general tendency with experiments. The main reason of inaccuracy is that the coupled dynamics of ship motion and internal water motion is not accurately accounted. In this study CFD technique based on VOF is employed for the accurate analysis of flooding water motion. Some cases of ITTC benchmark study for tanker with internal fluid are analyzed by coupling the ship motion and sloshing dynamics.
