A closer look at the drag curve for a circular cylinder near the onset of vortex shedding reveals that there is a sharp transition in the forces acting on a body moving through a fluid when it produces an unsteady wake. In this Letter results from high‐resolution computer simulations are presented to quantify the change in viscous drag, pressure drag, and base pressure coefficients.

Additional Information:© 1995 American Institute of Physics. Received 21 February 1995; accepted 1 May 1995. This question about the drag force grew out of discussions within the Bluff Body Wakes Group at GALCIT, and in particular with Anatol Roshko. The computations were performed at Caltech with the support of the National Science Foundation under Grant No. CDA-9318145, and the Office of Naval Research under Grant No. N00014-94-1-0793.
