Numerical Studies of Flows past a Cylinder and over a Hill Using the Detached Eddy Simulation (DES) Model

Popis výsledku v původním jazyce

The paper deals with a numerical simulations incompressible flow with the application of Detached Eddy Simulation (DES) turbulence model. For the numerical simulations were chosen problems flow past a cylinder, flow over periodic hill and flow over three-dimensional hill. These problems are used as benchmark for computational software. All simulations are computed by the means of unstructured grids, consisted from tetrahedral elements. In the frame of this study parameters such as geometries, computational grids resolutions and mathematical models are considered. Results such as time averaged velocity fields and Reynolds shear stress etc. are presented and good agreement with experimental data was found.
