Wave Characteristics of Water-Surface Planing Hull Form

Abstract

The present paper describes a method of predicting the hydrodynamic characteristics of high speed planing hull form by using a linear water-wave theory based on Neumann-Kelvin approach. The method is to solve numerically the source density distribution on the bottom hull, in which computational method of calculating wave Green function based on an approach using complex exponential formula. The computation is applied to a wedge shape planing hull form. The results of pressure distribution, pressure resistance, and wave resistance are in good agreement with the measured data which were obtained by the authors.
