PREDICTION OF SHIP WAVEMAKING RESISTANCE AND OTHER STEADY FLOW PARAMETERS USING NEUMANN-KELVIN THEORY

Developments in the calculation of ship wave resistance based on a Neumann-Kelvin mathematical model are briefly outlined. Although significant advancements have been recently achieved in modeling techniques, numerical analysis and computer implementation, the emphasis of this paper is on the application of the Neumann-Kelvin theory to a submerged prolate spheroid, a Wigley parabolic hull, an HSVA tanker, a Friesland destroyer and a cruiser hull form. For these hull forms, wave resistance, wave profiles, pressure fields, distributions of vertical forces, etc., were evaluated over wide ranges of Froude number and this paper presents a selection of predictions that are compared with experimental data and results derived from other theoretical models. It is clearly demonstrated that the Newmann-Kelvin predictions reflect the experimental data both quantitatively and qualitatively, describing with remarkable accuracy the characteristic variations of humps and hollows exhibited in a curve of ship wave resistance coefficient versus Froude number. In the present context, this is achieved using accurate and fast algorithms on computers of limited size and resource.
