Numerical solution to the flow of a micropolar fluid between porous walls of different permeability (Q1087063)

The problem of steady laminar micropolar fluid flow through porous walls of different permeability has been discussed. At the entry of the channel, the velocity and microrotation are considered as those of Poiseuille flow. The governing nonlinear ordinary differential equations have been solved using quasilinearisation technique. The velocity and microrotation are found to involve S, the suction Reynolds number of cross flow at the upper wall. The effect of different permeability at the walls, on the longitudinal velocity and microrotation has been studied. The skin friction and the couple stress on the walls have also been calculated.
