Theoretical and Numerical Study of Vortex-Wake Flow

This paper is to show a numerical and theoretical analysis of vortex-wake generation for flow past three circular cylinders. The three cylinders are positioned in a T-shape and spaced at length ratios (s/r) from 2 to 8 and the Reynolds number range from 100 to 800. The numerical results show characteristics of the wakes changing considerably with the length ratios. This research showed the numerical solution for flow over three cylinders in a T-shape arrangement. From the numerical results, such as the path lines, one can conclude that the vortex generation and the wake region are affected by the spacing between the cylinders. For the length ratio of 2.0 one can see that the drag is minimized.
