CALCULATION OF THE BOUNDARY-LAYER FLOW AROUND THREE SHIP AFTERBODIES
A description is given of a differential method for the calculation of the boundary layer on ship hulls, and its application to three slightly different ship afterbodies. The boundary layer equations are solved in a curvilinear coordinate system, together with two turbulence model equations. The results are compared with experimental data. The correspondence appears to be excellent on the greater part of the hull. In some regions, differences are present, which result mainly from the neglection of the potential flow-boundary layer interaction. The prediction of bilge vortex formation is examined, and the incorporation of higher order effects in the method is briefly discussed.
