Transport Phenomena in Rotating Turbulence

摘要

The role of rotation on turbulence and some of its transport properties will be reviewed with emphasis on two specific cases: statistically steady or decaying rotating turbulence and rotating thermally driven turbulence. For this purpose we briefly address a few basic concepts relevant for understanding processes in rotating (turbulent) flows such as the emergence of coherent structures, the Taylor-Proudman theorem, quasi-two-dimensional turbulence, inertial waves and Ekman boundary layers. The effect of rotation on turbulence will subsequently be illustrated with two sets of laboratory experiments: one with steadily forced rotating turbulence and another with rotating turbulent convection.
