Abstract

The effect of surface roughening on the onset of vortex motion in thermal counterflow in a rotating channel has been investigated. Smooth surfaced channels exhibit a critical counterflow velocity independent of surface characteristics. Rough surfaced channels exhibit a larger critical velocity, larger by just the amount necessary to bring the average vorticity at the surface parallel to the surface.
