Abstract

This paper presents the numerical estimation results of oil outflows from damaged single-hull and double-hull ships by using computational fluid dynamics (CFD) simulations. A CFD method for multi-phase flow analysis was used, and the effects of numerical parameters on oil flows was investigated. Numerical simulations were conducted to predict the changes in oil outflows under various damage conditions owing to grounding or collision accidents and verified through available experimental results. The present numerical results showed a good agreement with the experimental results according to the geometrical characteristics of single and double hulls. In particular, the oil outflows from double hulls accompanying complex interactions between water and oil were reasonably predicted a shown in the experiment. This study established a reliable CFD technique necessary for estimating the oil outflows of damaged ships.

본 논문은 CFD 해석법을 이용한 단일선체 및 이중선체 선박의 손상에 따른 기름 유출량 추정 결과를 소개한다. 수치해석 기법으로 다상유동 해석법을 사용하고 기름 유출 유동에 대한 다양한 수치해석적 조건의 변화에 대한 영향을 조사하였다. 좌초 또는 충돌에 의한 다양한 손상 조건에서의 기름 유출량의 변화를 해석하였으며 실험 결과를 통해 검증하였다. 본 논문의 수치해석 결과는 단일선체와 이중선체의 기하학적 특성을 따라 실험 결과와 잘 일치하였다. 특별히 물과 기름의 복잡한 상호작용이 나타나는 이중선체의 기름 유출 상황도 실험과 동일하게 타당하게 예측하였다. 본 연구를 통해 사고 선박의 기름 유출량 추정에 필요한 CFD기법을 정립할 수 있었다.
