HYDRODYNAMIC COEFFICIENT CALCULATION USING DOUGLAS POTENTIAL FLOW COMPUTER PROGRAM

Abstract

A new method is presented for calculating the hydrodynamic coefficients of axisymmetric bodies. The method utilizes an extended version of the Douglas potential flow computer program for axisymmetric bodies to calculate the potential and velocity distribution along the body required for the determination of the forces and moment acting on the body. Based on a comparison with experiment limited to one body shape, the method yields values of the hydrodynamic coefficients for blunt- or flat-based bodies which are adequate for most engineering work.
