Abstract

In engineering areas such as chimneys, bridges, nuclear power plants, airplanes, submarines and high buildings are exposed to fluid or gases flows. As we know there is amount of vibrations, loads, vortexes around of bodies which are exposed flows. Also these undesirable situations are required some solutions. n this regard for solutions of such that problems, analysis of flow around bodies with regard to velocity distribution, streamlines, vortexes is a significant issue. From this perspective because of its easy geometry, flow around of cylinder has been investigated on account of velocity distribution, streamlines, vortexes for different fluids and Reynolds numbers by means of Anysis CFX 14.5. Laminar and steady flow was handled for two different cases. Case 1 and case 2 are differs from each other in term of boundary conditions for related fluids and Reynolds numbers. Finally from results in question vortex zones, velocity and pressure distribution and drag coefficient of both cases are compered for case 1 and case 2.
