It is observed that, as the porosity of the bounding surface increases the velocity also…show more content…
Fig 16 and fig 17 shows the consolidated effect of Prandtl number and porosity on the skin friction. In each of these cases, in general the Prandtl number and skin friction are inversely related to each other.
