SORET AND DUFOUR EFFECTS ON MIXED CONVECTION FLOW OF COUPLE STRESS FLUID IN A NON-DARCY POROUS MEDIUM WITH HEAT AND MASS FLUXES

An analysis is presented to investigate the Soret and Dufour effects on mixed convection heat and mass transfer along a semi-infinite vertical plate embedded in a non-Darcy porous medium saturated with couple stress fluid with flux distributions. The governing nonlinear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations and then solved numerically. Profiles of dimensionless velocity, temperature, and concentration are shown graphically for various values of Dufour number, Soret number, and couple stress parameter. Nusselt number and Sherwood numbers are calculated and presented in table form.
