Details of the drag curve near the onset of vortex shedding

Name: Work Video:
Duration: 3 min 30 s
Description: 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.
