• Fully-developed turbulent flow in a rotating channel is simulated numerically by means of Large-eddy Simulation (LES). It is intended to supplement the difficulty of experiments of this type of flow with numerical analysis. LES is successfully applied to reasonably reproduce notable features of the effects of Coriolis force on the turbulent shear flow and its structure. Namely, the stabilization of the flow on the suction surface and the intensification of turbulence on the pressure surface by Coriolis force are confirmed. Also, modification of the time averaged flow due to the above effect is demonstrated in detail. It is also suggested that the subgrid-scale model of a very low intensity turbulence must be improved.
