..., the average velocity over the thin film thickness is not equal to 0.5 U w and the shear stresses on the upper wall ( S 3 ) and on the lower wall ( S 4 , S 6 ) are different. Nevertheless, except for the interface between the channel flow and the cavity ( S 5...

.... A Computational Fluid Dynamics (CFD) commercial code was used to simulate flat-plate-channel-flow experimental tests of water flowing with deliberately roughened surfaces, showing an increase of friction factor with clearance increase. The higher friction factor characteristics of these deliberately roughened...
