Abstract

In this paper we present some initial results of a fourth-order direct numerical simulation of flow past a square cylinder at Re = 22,000. The flow is identical to the second test case which is considered at this workshop. Mean velocities, the mean Strouhal number, the mean drag coefficient Cd, the mean lift coefficient C1 and the rms fluctuations of Cd and C1 are computed.
