주파수집중법에 의한 FPSO 선수부 파랑 충격 수치계산에 대한 CFD 모델링 수치계산방법연구

Abstract

Computational Fluid Dynamics (CFD) simulation methodologies for FPSO bow impact calculation were consolidated in a Joint Development Project (JDP). To validate the proposed simulation method, a series of model test performed for the bow wave impact problem by focusing wave was considered. First, wave generation performance was checked by applying the present CFD simulation method. In this case, the measured stroke signals of the wave maker in the model test were directly used as input of the inlet velocity boundary. Then, the numerical simulations results for wave impact forces were validated by comparing with the model test data. It is confirmed that FPSO bow impact prediction using the consolidated CFD simulation guideline is fairly good in overall physical process and wave impact forces.
