Abstract

This article treats analytically, the magnetohydrodynamic flow through non-parallel porous walls or between two solid porous plates intersecting at an angle, that can be interpreted as a combination between the classical Jeffery Hamel flow added of one injection/suction. The governing equations of the problem are converted from traditional Navier-Stokes equations of fluid mechanics accompanied by those of Maxwell's electromagnetism to ordinary nonlinear differential equations for modeling.Asemi-analytic solution is developed by using Homotopy Analysis Method (HAM) whereas the numerical solution is presented by Runge-Kutta scheme. A comparative study between the analyticaland numerical solutions is made. The results confirm clearly that the two methods coincide closely fordifferent angles (α), Reynolds numbers (Re), injection parameter (S) and Hartmann number (Ha).
