A Calculation Method for Ship Stern Flows Using an Analytical Body Fitted Coordinate System

Paper i proceeding, 1984

A new method for calculating ship stern flows is described. The method is based on the thin boundary layer equations cast in an analytic, body-fitted coordinate system. The major part of the paper deals with the definition and generation of this system and the computation of the related metrics and Christoffel symbols. Derivations of the governing flow equations are also made, using tensor algebra, and a short account is given of the numerical solution method. Finally, results from some test calculations are presented.
