Abstract: In this paper, the onset of vortex shedding and flow configurations over two equal square cylinders in tandem arrangement are carried out on a finite volume code based on the SIMPLEC algorithm and non-staggered mesh for both steady and unsteady incompressible laminar flow in the two dimensional regime. The calculations are performed for a Reynolds number range varying from 1 to 200 and spacing between the cylinders is five widths of the cylinders. The mesh is finer close to the cylinders walls in order to have a better description of boundary layer. In this research, the influence of Reynolds number and the onset of vortex shedding on the flow patterns around the cylinders are presented in detail. In addition, the quantities such as pressure and viscous drag coefficients, RMS lift and drag coefficients, recirculation length and phase lag are presented and explained. It is found that the onset of vortex shedding occurs for a Reynolds number varying 35 to 40.
