This study is concerned with both hydrodynamic and
hydromagnetic unsteady slow flows of two immiscible visco-elastic fluids
of Rivlin-Ericksen type between two porous parallel nonconducting plates
inclined at a certain angle to the horizontal. The exact solutions for the
velocity fields, skin frictions, and the interface velocity distributions are
found for both fluid models. Numerical results are presented in graphs.
A comparison is made between the hydrodynamic and hydromagnetic
velocity profiles. It is shown that the velocity is diminished due to the
presence of a transverse magnetic field.
