Berman developed the fourth-order nonlinear differential equation with initial and boundary conditions. This model
is based on two-dimensional, steady, incompressible viscous fluids that flow through the permeable channel with wall
suction/Injection. The solution of this model is semi-analytically computed by optimal Homotopy asymptotic technique
(OHAM). Reynolds number is based on Suction or injection through the wall, so for different values of Reynolds, we
obtained different types of semi-analytic solutions by OHAM.
