Flow Over Backward Facing Step with Inclined Wall Solved by Finite Volume and Finite Element Method

Popis výsledku v původním jazyce

The work deals with numerical solution of 2D incompressible flow over backward facing step. The inclination angles of the upper wall of the channel were chosen as in measurements by Driver and Seegmiller. Two numerical methods are considered. One is finite volume method, the other one is finite element method. Turbulence is modeled using two-equation turbulence models of k-? type. The influence of outlet boundary condition is discussed and do-nothing-like condition found suitable also for finite volumemethod. The comparison of both methods is presented for laminar as well as turbulent cases, including experimental results. The differences of the results are studied using one turbulence model and both numerical methods or one method and more turbulencemodels. It is found that sensitivity of the computation to these circumstances increases for higher inclination angles (diffuser flow).
