Abstract

An unsteady free convective flow of visco-elastic fluid though a porous medium has been investigated in presence of Hall effects. Constitutive equation of visco-elastic fluid is governed by Walters liquid model for short relaxation memories. The medium is rotating with a constant angular velocity. A magnetic field of uniform strength is applied along the transverse direction to the surface. Conservation laws of mass, momentum, energy and species concentration are formed mathematically using suitable approximations. Governing equations of motion are solved analytically using perturbation scheme. Results are discussed graphically and numerically for various values of flow parameters involved in the solution.
