.... The results physically imply that magnetic field accelerates the fluid particles in the vicinity of the wall reducing the momentum boundary layer thickness, while enhancing the skin friction. Moreover, couple stress fluid is shown to yield less wall shear stress as compared to a regular Newtonian fluid...

...N. Rostamy; D. J. Bergstrom; D. Sumner; J. D. Bugg The effect of surface roughness on the mean velocity and skin friction characteristics of a plane turbulent wall jet was experimentally investigated using laser Doppler anemometry. The Reynolds number based on the slot height and exit velocity...
