Because of costly large-scale real test as an alternative and less costly than going to the numerical simulation.In the real world, and many in the industry to form cylindrical structures that are in the current path.Industrial factory chimneys and foundations of bridges are real-world examples.In this paper, the unsteady flow, viscous, incompressible, two-dimensional inside a cylindrical channel with obstacles is simulated.Profile fluid flow around the cylinder for different flow regimes of different slot through several calculations have been achieved.In general, different flow patterns for different gap ratios and different Reynolds numbers has been observed.In this paper, the flow field become smaller areas and using Fluent software Cantor various fields of pressure and speed, Vorticity and well show flow lines.Several elements have been studied for the independence of the network and the most suitable option has been used for the final analysis.
