On an Important Remark Concerning Some MHD Motions of Second-Grade Fluids through Porous Media and Its Applications

In this work it is proven that the governing equations for fluid velocity and non-trivial shear stress corresponding to some isothermal MHD unidirectional motions of incompressible second-grade fluids through a porous medium have identical forms. This important remark used provide exact steady-state solutions with on boundary when similar are known. Closed-form expressions provided both Darcy’s resistance. As check results obtained here, over an infinite flat plate presented in different forms whose equivalence graphically proven. case between parallel plates, behavior symmetric respect median plane due conditions.
