Abstract

A multiparameter conformal mapping technique is presented which permits the accurate description of realistic ship sections. The solution of a nonlinear set of equations describing the transformation of a circle to the arbitrarily shaped section s linearised using a new method which produces a monotonic relationship between coordinates in the physical and reference planes. This feature allows the mapping of reentrant sections such as large bulbous bows and the inclusion of features such as bilge keels and shaft brackets. The assumed form of the conformal mapping permits asymmetric sections to be represented. The sections can be successfully transformed at different heel angles.
