On the Similarity of the Wake of the Steady Flow around a Circular Cylinder

Abstract

The steady flow around a circular cylinder is numerically investigated. The solutions are obtained at Reynolds numbers of 40, 100, 200, 400, 500, 700 and 1000 by an implicit finite-difference approximation. The similarity of the shape of standing vortices is confirmed at Reynolds numbers from 20 to 100, and the similarity of the velocity distribution along the flow axis in the standing vortices is confirmed at Reynolds numbers from 15 to 100.
