Mixed Convective Elastico-Viscous Fluid Flow Past a Porous Plate in Presence of Induced Magnetic Field and Energy Dissipations

A mixed convective hydro-magnetic flow of visco-elastic fluid past an infinite vertical porous surface with constant suction has been investigated in presence of heat and mass transfer. Visco-elastic fluid flow is characterized by Walters liquid (Model B') for short relaxation memories. A magnetic field of strength B₀ is applied along the transverse direction to the surface. To study the governing fluid motion, we have considered the effects of induced magnetic field and magnetic dissipations of energy. Mechanism of heat transfer arises from mixed convection along with dissipation of energy due to viscosity. Let T_w and C_w be respectively the temperature and the molar species concentration of the fluid at the surface. To solve the governing equations of motion, we have used multi-parameter perturbation scheme. Two non-dimensional numbers taken as perturbation parameters are Eckert number and visco-elastic parameter. The results are discussed graphically for the various values of elastico-viscous parameter along with other values of flow parameters involved in the solution.
