The unsteady Poiseuille flow of a viscoelastic fluid between two horizontal porous plates in the presence of a porous medium is studied with heat transfer. The fluid viscosity is assumed to be temperature dependent and the fluid is subjected to a uniform suction from above and injection from below. The plates are maintained at two fixed but different temperatures. The motion of the fluid is produced by a uniform horizontal constant pressure gradient. The equation of motion and the energy equation are solved numerically to yield the velocity and temperature distributions.
