Magnetohydrodynamic (MHD) flow analysis of second grade fluids in a porous medium with prescribed vorticity

Steady and unsteady flow of a second grade MHD fluid in a porous medium with Hall current effects is studied. Assuming an a priori known vorticity proportional to the stream function up to an additive uniform stream, exact solutions for velocity field are obtained corresponding to different choices of pertinent flow parameters. Graphical results are presented to depict the influence of pertinent flow parameters on the considered MHD flow. (C) 2015 Author(s).
