Abstract: Experiments are presented to characterize low- and high-drag turbulence events in channel flows close to transition, which last for a certain duration, at friction Reynolds numbers ranging from $$Re_\tau\,=\,$$Reτ= 70–100. The spatiotemporal intermittencies are identified by… read more here.

Abstract: An experimental investigation is conducted on the active drag reduction (DR) of an Ahmed body with a rear slant angle of 35°, corresponding to the low-drag regime, using single and combined actuations at the Reynolds… read more here.
