Testing Auxiliary Pointers to Stabilize the Numerical Simulations
Original language description
In this contribution we describe simulations of laminar and turbulent incompressible flow by the created model which is tested for several significant influences, such as stability coefficients (CFL), different computational areas, staggered grids etc. To solve the equation system on limited area the finite control volume method is employed. The initial value problems and boundary conditions on control volumes are described and discussed in some numerical examples, e.g. liddriven cavity flow and three-dimensional Taylor-Green vortex (TGV) for the low and high Reynolds numbers. The used model consists ofthe Navier -Stokes equations for the laminar flow and the continuity equation in the form for incompressible fluid flow. The conservative high order methods are used for solving the system of the equations describing the conservation laws. The advection terms are reconstructed using the 5th order weighted essentially non oscillatory (WENO) scheme and the time evolution is solved by the a
