Numerical Modeling of 2 D and 3 D Flows using Artificial Compressibility Method and Collocated Mesh
In this paper, applications of a numerical model on simulation of two and three dimensional flows are presented. This model solves Navier Stokes equations using finite volume method and large eddy simulation (LES) in a collocated mesh. Artificial c ompressibility m ethod w ith d ual t ime stepping is used to solve the time dependent equations. Also a modified m omentum i nterpolation method (MIM) based on the unsteady flows i s deployed t o overcome t he non physical pressure oscillation. Capability of the presented numerical code for flow s imulation, i s assessed by application for twodimensional square and three dimensional lid driven cavity flows. Numerical results of cavity flow presents very good agreement with the numerical and experimental data of other existent researches.
