Abstract:

Special approximations are needed in order to analyze the free surface flow in the vicinity of the bow of blunt ships. In the case of thin ships the inner bow flow reduces to a two-dimensional flow in a vertical plane normal to the bow. The situation at the confluence of a blunt bow and the free surface is clarified first. It is shown that there are two possible angles between a free surface and a rigid wall at the stagnation point 1 if the wall is inclined with respect to the horizontal at an angle larger than 120 deg, the free surface intersects the wall at 120 deg 2 if the wall is inclined at less than 120 deg, the free surface is horizontal. The latter case is usual for ships.
