NUMERICAL ANALYSIS OF THE VISCOUS FLOW FIELD RESULTING FROM A HULL- SAIL INTERACTION

The corner vortex originating in the hull-sail intersection region is an important component of the submarine flow field. The vortex may play a major role in overall drag, wake development and propeller performance, and may be a major acoustic source. The flow itself is a complex one, being three-dimensional, viscous and turbulent. This paper focuses upon the portion of this flow field downstream of the sail leading edge. It first details the analysis that is based upon a three-dimensional, viscous, spatial forward marching approach. The solution procedure, which is based upon ADI techniques, is described. The discussion then proceeds to the coordinate system, initial conditions and boundary conditions. Finally, calculations for both laminar and turbulent flows are presented.
