Abstract
The article deals with the numerical simulation of the flow pattern around a moving body in a stratified fluid. The flow is assumed to be unsteady, incompressible and stratified. The mathematical model is based on the Boussinesq approximation of the Navier-Stokes equations for viscous incompressible flow wit non-constant density. The resulting set of PDE's is then solved by the AUSM MUSCLE scheme in finite volume approximation. For the time integration the three stage BDF method of the second order is used. Three different obstacle models were tested.
