Steady flow past a circular cylinder with parabolic velocity distribution at high reynolds numbers - A numerical study

Abstract

A steady, viscous, incompressible flow past a circular cylinder is studied numerically at moderately high Reynolds numbers. A variable shear flow with velocity curvature factor G is taken as the incident flow. The drag coefficient is calculated at Re = 1000 and 2000 with G = 0, 0.1 and 1.0. The results for G = 0, which correspond to uniform flow, are compared with the existing results for Reynolds numbers upto 500. The non-zero curvature is found to affect the breadth of the wake bubble, the separation angle and the drag coefficient.
