Abstract
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 compressibility method with dual 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 a ssessed by a pplication f or twodimensional square and three-dimensional lid-driven cavity flows. Numerical r esults of cavity flow presents very good agreement with the numerical and experimental data of other existent researches.
