Abstract

In this work we have investigated a numerical study of unsteady two-dimensional turbulent flow of incompressible fluid around and behind a cylinder with various diameter (𝐷1=50𝑚𝑚, 𝐷2=100𝑚𝑚) 𝑎𝑡 𝑅𝑒=10×103 𝑎𝑛𝑑 𝑅𝑒=30×103, respectively. A numerical simulation will be used by CFD code to visualize the phenomenon of turbulent wakes generated behind a cylinder and the separation region around the surface cylinder. The standard 𝑘−𝜀 model is the numerical method used to manage the turbulent flow. This study led us to focus on the velocity contours, pressure contours, the static pressure distribution along the x-direction, the profiles of skin friction coefficients, and the variation of drag and lift coefficients as a function of time. The results obtained for the two cases considered gave us satisfactory results. The development of an oscillation region behind the cylinder, the variation of static pressure and skin friction coefficient along the cylinder, the mean velocity fields, pressure fields, all will be captured by the present.
