고속활주선 선형이 바닥압력에 미치는 영향

Abstract

To estimate the hydrodynamic performance of high speed planning hulls, it is important that running attitudes should be accurately calculated during planning. To calculate the running attitudes, bottom pressure should be accurately calculated. If we predict the bottom pressure distribution using relation between pressure and hull form, it is helpful to design planning hulls. In this study CFD calculations were performed with snuFoam based on openFOAM, bottom pressure distributions were analyzed characteristics on the planning hulls depending on hull forms and forward speeds.
