DETAILED BOW-FLOW DATA AND CFD FOR A SERIES-60 C-B=0.6 SHIP MODEL FORFROUDE-NUMBER 0.316

The bow flow of the Series 60 C-B = 0.6 ship model is reinvestigated u sing both experiments and computational fluid dynamics (CFD). More det ailed bow-flow data are obtained by taking measurements of the wave el evation with a point gauge very near the bow. In the CFD, the bow flow is resolved in more detail by using the real bow geometry instead of the simplified vertical zero-thickness bow used in previous studies, w hich requires a much finer grid in the bow region. The experiments and CFD are briefly described; results are presented; and discussions are made concerning comparisons of the new and old CFD solutions with the extended data regarding the wave profile and elevation at the bow, th e thin film and beads (i.e. attached spray sheet and bow vortices), an d the stagnation effects.
