Abstract

A flow simulation is presented for a 2D channel with different Reynolds numbers (Re = 5600, Re = 13750). Additionally a parametric analysis is carried out for different meshes depending on various Reynolds number values. Computational experiments are carried out to compare the ANSYS CFX and Fastest-3D software packages. The k-Ј, k-o, SST, low-Re WJ and low-Re CLS EARSM turbulence models are used in the experiments.
