Abstract:

 This work consists to study numerically the phenomena of two-dimensional
incompressible laminar flows around two tandem circular cylinders of various diameters. Five
cases of flow with various hydraulics diameters are simulated. The first cylinder has a fixe
diameter D, while the diameter of the second will change between D/4 and 4D, the distance
between cylinders is fixed at L=4D. From these simulations, particularly in the area of
interference and downstream wake area of the cylinder, the results demonstrate clearly the
influence of the diameter on the flow structure. We visualized the phenomenon of Van Karman, the
behavior of fluid particles is characterized by sudden destruction of the vortices downstream of the
wake. To provide a better understanding of the dynamics of vortex, the pressure distribution
contours, velocities depending on the diameter and the Reynolds number, Re are presented and
discussed.
