OPTIMAL SHIP FORMS FOR MINIMUM BOW WAVES

The flow around slow, full-form ships with large bulbous bows is investigated based on the asymptotic analysis of the low-speed limit with a small parameter representing the slowness of a ship defined by U to the 2nd power/2g. A computer program based on Webster's (1975) method of submerged triangular source patches has been developed to compute the flow around arbitrary three-dimensional bodies in an infinite fluid. The free-surface disturbance function D(x,y) induced by the double-body potential has been examined for several bulbous bow models. It is shown that, contrary to Baba's (1975) hypothesis, ship forms having smaller D(x,y) do not necessarily yield better wave-breaking resistance characteristics.
