Vortex Shedding from Finned Circular Cylinders

Abstract

A computer program has been developed to simulate vortex shedding from circular cylinders with evenly distributed fins. These bodies may rotate continuously or oscillate in a parallel stream. The two-dimensional flow model consists of point vortices inserted in an otherwise potential-flow field. For the roll-up of the line of vortices the rediscretization scheme by Fink and Soh is used. Sample results are presented for vortex shedding from a flat plate at angles of attack of 45 deg and 90 deg, and from a circular cylinder with two fins at an angle of attack of 45 deg.
