Comparison of Three Different Obstacle Models for Modeling of Stratified Flows over the Body
Original language description
The article deals with the numerical simulation of the stratified incompressible flows over the body. The mathematical model is based on the Boussinesq approximation of the Navier--Stokes equations for viscous incompressible stratified flow. Three different numerical approaches to the body are implemented and tested. The first one is the classical body fitted mesh. The second one is the penalization technique. The obstacle is modeled as the permeable obstacle with high resistance parameter. The last approach is based on the immersed boundary method. 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.
