This paper describes the results of our recent investigation on the effects of turbulence on the mean flow past 3D and 2D bluff bodies. Emphasis is placed on finding possible effects of turbulence scale. It is shown that turbulence can significantly influence bluff-body mean flow at two main scales. Small-scale turbulence causes the separated shear layer to reattach earlier on the side face of a bluff body through enhanced mixing. Large-scale turbulence interacts with vortex shedding from a bluff body, thus changing the mean flow considerably.
