해양 기계 시스템 거동 예측을 위한 자유표면 유동을 고려한 FSI 해석 사례

Abstract

This study was conducted to introduce FSI analysis techniques and cases including free surface for application to offshore green hydrogen production platform. In order to analysis fluid flow distribution, the non-staggered, non-orthogonal, and unstructured grid system were used. For the lid-driven cavity flow and solitary wave propagation flow are carried out for validating CIP solver. Test results show a good agreement with the verified results. The dynamic solver was used for the behavior of moving body. Interface process between the two solvers is introduced. We would like to introduce various analysis cases to which FSI is applied.
