CALCULATION OF NONLIFTING POTENTIAL FLOW ABOUT SHIP HULLS

A practical method is described for calculating the non-lifting potential flow about ship hulls. The method utilizes a continuous source density distribution on the surface of a ship, and treats the normal component (or integral equation for the source density distribution), radial component and circumferential component of disturbance velocity as two dimensional problem by assuming the slender body, but treats the longitudinal component as three dimensional problem because of difficulty in applying the slender body assumption. The accuracy of the method is exhibited by means of comparison with the full three dimensional solution by Hess and Smith. As some examples of application, sinkage force, side force and added mass are calculated for Series 60 ship hull.
