Mixed convection flow of couple stress fluid between vertical parallel plates with radiation and chemical reaction effects

Abstract

Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.This paper studies the effects of thermal radiation and chemical reaction on two dimensional incompressible couple stress fluid flow with mixed convective heat and mass transfer between two vertical parallel plates in a porous space. The plates are kept at different but constant temperature and concentrations. The governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations. The resulting equations are then solved using the homotopy analysis method. The effects of the radiation parameter, chemical reaction parameter and couple stress fluid parameter on velocity, temperature and concentrations are discussed and shown graphically. Also the effects of the pertinent parameters on the rates of heat and mass transfer are tabulated.
