Effects of Coriolis Force on the Turbulent Boundary Layer with Pressure Gradients

概要

Distribution of velocities and turbulent intensities in turbulent boundary layers developed in a diffuser were studied experimentally when the diffuser was rotated about an axis perpendicular to it. With and increase in the opening angle of the diffuser, the turbulent intensities and the time mean velocity gradient were increased more near the pressure side wall, but decreased near the suction side wall due to the effects of the Coriolies force. On the pressure side wall, turbulent intensities were enhanced by the rotation, and the Monin-Oboukov formula was ascertained to be approximately established within the experiment range even in an adverse pressure gradient.
