ANALYSIS OF THE BULBOUS BOW ON SIMPLE SHIPS

Abstract

The mathematical expression of the wave resistance of a conventional ship is extremely complicated. Except for the special cases of very low or very high Froude numbers it is necessary to integrate a highly oscillating function numerically. And it is extremely difficult to investigate the effect of varying parameters in the wave resistance equation. Therefore, only simple models of ships are considered in the present paper. The advantages of this procedure are: (1) we can analyze not only the wave resistance but also the effect of the size and the location of the bulb; (2) we need not be concerned about the effect of linearizing the boundary condition on the ship surface; and (3) we can investigate the fundamental relationship between the source and doublet under the free surface.
