Unsteady Flow of Non-Newtonian (Oldroyd (1958) Model) Fluid with Transient Pressure Gradient through Porous Media in A Rectangular Channel

The aim of the present paper is to investigate the unsteady flow of non-Newtonian Oldroyd model fluid of second order with transient pressure gradient through porous media in a long rectangular channel. The expression for velocity of the fluid is obtained in elegant form. The various deductions have also been discussed in detail.
