Abstract

System rotation may drastically change the flow behavior both for laminar and turbulent shear flows clue to the effect of the Coriolis force. For plane Poiseuille flow the Coriolis force acts in such a way that in the part of the channel where the system rotation has opposite sign compared to the mean fiow vorticity the flow becomes destabilized whereas in the other part of the channel it becomes stabilized. Alfredsson & Persson (1989) showed that the instability takes the form of streamwise oriented roll cells and demonstrated excellent agreement between linear theory and experiments.
