POTENTIAL FLOW NEAR TO A FINE SHIP'S BOW

A more accurate method is used to solve the bow flow problem formulated by Ogilvie (1972). The new method of solution satisfies the body boundary condition on the actual surface of the hull near to the bow. Numerical results were obtained for the wave heights along cuts parallel to the side of the wedge. The contour maps of the wave heights show an outward shift of the waves proportional to the wedge half angle relative to the pattern due to thin ship approximation. The wave amplitudes agree fairly well with the experimental results for a fine bow at moderate values of the draft-based Froude numbers. /Author/
