Reynolds-Stress Model Taking into Account Strong Anisotropy of Wall Turbulence (2nd Report) Assessment of the Model

概要

A new Reynolds-stress model developed by the author is assessed for the computations of turbulent Couette flow and turbulent rotating channel flow. The turbulent Couette flow has two distinctive properties. In the wall layer, the flow is wall turbulence, but the flow is also plane homogenous shear flow in the core region. The turbulent rotating channel flow is affected by Coriolis forces associated with the rotation. There is no direct effect of rotation on the turbulence energy budget, but in the budget for the Reynolds-stress tensor, the rotational term appears explicitly. Thus, the two flows are suitable for assessing the Reynolds-stress model. Computational results are compared with the available experimental data, proving that the performance of this Reynolds-stress model is effective.
