Abstract
Fully-developed turbulent flow in a channel rotating about a spanwise axis is calculated using a Reynolds stress model. The model is a slightly modified version of the second-moment closure applicable right up to a wall which was developed by the author in previous papers. The numerical solutions are compared with available experimental data on the mean velocity profiles and the wall shear stresses and also with large eddy simulation (LES) results on the turbulent normal stresses. When the Rossby number is lower than about 0.1, the predictions are in good agreement with the experimental data and the LES results, capturing the stabilizing and destabilizing effects of Coriolis forces on the flow. For Rossby numbers greater than the value, however, the calculations fail to reproduce the experiments, which suggests a need for a separate study.
