Notizen:
A numerical investigation of the flow of two immiscible stratified fluids under an isolated keel has been undertaken. The investigation utilized the two-dimensional Euler equations for incompressible flow, and the solution of these equations has been obtained by using the well-known finite volume marker and cell approach. Experimental drag-force measurements are also presented for a family of two-dimensional topographic models of fixed height with increasing surface slopes in a two-layer density system. The range of flow speeds explored covers the Froude number range from subcritical to fully supercritical. The drag force measurements are augmented by detailed observations of the interface distortion. The results clearly show large drag increases arising from the internal wave systems generated in the stratified flow. Very good agreement has been found between the experimental and numerical results for both the interface shape between the two fluids and the drag force on a variety of keels.
