Abstract
Coriolis effects on fully developed turbulent flow in a two-dimensional channel rotating about an axis perpendicular to its axis are considered. The Coriolis force has stabilizing/destabilizing effects on turbulence, and the mean velocity distribution changes accordingly. Experimental and numerical studies on the velocity characteristics have already been conducted by other researchers for various conditions. However, we cannot assemble the overall picture of the Coriolis effect on the velocity distributions. In this paper, analytical studies have been performed using dimensional analysis, which indicates that the three lenght scales and their ratios constitute the dominant parameters governing the flow. The flow regime space has been shown to account for the overall Coriolis effect on the flow. Furthermore the velocity laws for various flow regions have been derived.
