Abstract:
In the present abstract, DNS results obtained for turbulent plane Couette flow with wall-normal transpiration velocity are presented. Important equations valid in such a flow are derived, describing the total shear stress and the relation between the friction velocities at the lower and upper wall. These expressions are of importance, as there are neither experimental nor DNS data to compare with. Equally important, we derive a center region and a viscous sublayer velocity scaling for the suction wall, which were both validated using the DNS data.
