Computation of wave-making resistance of Wigley hull form using michell’s integral

Abstract

The aim of the present paper is to compute the wave-making resistance of the Wigley mathematical hull of different cross-sections (parabolic, rectangular and triangular). Michell gave the first approximate hydrodynamic solution to the problem of wave resistance experienced by a slender ship-shaped body moving on the surface of an inviscid fluid of infinite depth. Based on Michell’s integral a computer program has been developed and executed in order to analyze the hydrodynamic characteristics of ships in an unbounded liquid and the validity of the computer scheme is verified by comparing it with the experimental results.
