- Flow around a circular cylinder is a fundamental fluid mechanics problem of practical importance. The dynamic characteristics of the pressure and velocity fields of unsteady incompressible laminar and turbulent wakes behind a circular cylinder are investigated numerically and analyzed simulation. The governing equations, written in the velocity pressure formulation are solved using 2-D finite volume method. In the present work is based on the cylinder diameter 102 Reynolds number for flow analysis slow and also turbulent based on the diameter of the cylindrical Reynolds number 105 as well as for the analysis of the flow around a cylindrical has been considered. The aim of this research is to investigate the influence of Reynolds number on flow parameters and verify the correctness of the calculations carried out by the governing equations of fluid mechanicsflow. Research on the hydraulic parameters of the flow around a cylinder help of ANSYS software. The frequencies of the drag and lift oscillations obtained theoretically agree well with the experimental results. The pressure and drag coefficients for different Reynolds numbers were also computed and compared with experimental and other numerical results. Due to faster convergence, 2-D finite volume method is found very much prospective for turbulent flow as well as laminar flow.
