Abstract

Surf-riding/broaching is a dangerous event for high-speed ships running in stern quartering seas. Theoretical methods for the prediction of wave-induced forces on ships in surf-riding and broaching situations are still of the qualitative level. Therefore, an unsteady Reynolds-averaged Navier–Stokes computational fluid dynamics (CFD) solver with overset grids was applied to predict the wave-induced forces on ships in irregular stern quartering seas. To validate the CFD method, a dedicated model experiment was conducted for slender ships, and the wave-induced forces were measured to be for a direct comparison with CFD predictions using the same irregular waves encountered. The comparison results indicate good agreement between the CFD results and the experimental fluid dynamics (EFD) results except for the wave-induced roll moment. •Unsteady RaNS simulation was applied to predict wave-induced forces on ships in irregular stern quartering seas.•A dedicated model experiment was conducted for slender ships in a large wave basin.•CFD results of wave-induced forces using the same encountering irregular waves were validated.•Sensitivity of grid points on CFD accuracy of wave-induced forces was investigated.
