Abstract

This paper studies the effect of ship bow shape on ridge resistance in a narrow ridge by using 3D discrete element method (DEM). A series of simulations on a ship passage through a narrow ridge are performed with different bow shapes, characterized by the bow angles: waterline angle, stem angle, and flare angle. By analysing the relation among the bow angles, the simulated ridge resistance, and the work needed for passing a ridge, we observe that the peak ridge resistance and the work both are increasing with an increase in any of the bow angles. The general features of the ridge deformation patterns are observed to be related to the ridge resistance records.
