Abstract:
In this work, we have investigated the laminar flow in porous channels applying
transverse magnetic field on it. We have reviewed the work of Suryaparkasarao et
al.\cite{surya} in detailed. Suryaparkasarao et al. did this by reducing the order of the
main equation to third order nonlinear differential equation which was derived after the
simplification of Navier stokes equation and continuity equation. They have calculated
the velocity components, pressure distribution and skin friction coefficients. Noreena et
al. have solved same problem in two different ways. In the first part, they solved the
forth order non-linear differential equation in a simplified way without reducing its
order. In second part, they have employed Homotopy Perturbation method which is
better approximation then regular perturbation method. We discuss the same problem
with a different technique is known as Optimal Homotopy analysis method (OHAM).
Finally, we compute the velocity components and compare these results .
