AN APPLICATION OF THE NUMERICAL TECHNIQUES TO PREDICT THE FLOW FOR HULL FORM DESIGN

A numerical procedure developed for calculating the flow field around ship hulls is described. Preliminary results are obtained in the initial stage by using potential flow double model calculation coupled with the modified Michell Theory. More precise results and a wave profile are achieved by utilizing a wave resistance program based on Dawson's method. Viscous flow is predicted via the thin boundary layer hypothesis for the main part of the hull length, while the differential equations for the rear part of the hull are solved with an elliptic method. Comparisons are made between numerical results and experimental data.
