Numerical simulation of flows over 2D and 3D backward-facing inclined steps

Popis výsledku v původním jazyce

The work deals with the numerical solution of incompressible turbulent flow in a channel with a backward-facing step having various inclination angles. Also, the inclination of upper wall is considered. The mathematical model is based on the Reynolds averaged Navier?Stokes equations. The governing equations are closed by the explicit algebraic Reynolds stress (EARSM) model according to Wallin and Johansson or by linear eddy viscosity models. The numerical solution is carried out by the implicit finite-volume method based on the artificial compressibility and by the finite-element method and both approaches are compared. The numerical simulations were tested by experimental data of Makiola and Driver, Seegmiller in large aspect ratio channels where results are obtained by 2D and 3D simulations. Further, PIV experimental data in a narrow channel are used for comparison with 3D simulations.
