Organized structures in rotating channel flow

The paper summarizes the major observations made from a series of computer experiments on rotating channel flows, emphasizing the influence of the Coriolis force on the organized flow structures. Roll-cell formation in turbulent Poiseuille and Couette flow is considered. The localized flow structures are also affected by the Coriolis force. Possible implication s of the organized structures for conventional turbulence modelling are finally addressed.
