Two Numerical Schemes for Simulation of the Stratified Flows Past a Moving Body
Original language description
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. Initial system of equations is the Boussinesq approximation of the Navier-Stokes equations. The flow field in the towing tank with a moving sphere and flat strip is modeled for a wide range of Richardson numbers. The obstacle is modeled via penalization technique. The resulting set of partial differential equations is then solved by the fifth-order finite difference WENO scheme, or by the second-order finite volume AUSM MUSCL scheme. For the time integration, the second-order BDF method was used. Both schemes are combined with the artificial compressibility method in dual time.
