Mixed Convection Flow of Couple Stress Fluid in a Non-Darcy Porous Medium with Soret and Dufour Effects

並列摘要


An analysis is presented to investigate the Soret and Dufour effects on the mixed convection heat and mass transfer along a semi-infinite vertical plate embedded in a non-Darcy porous medium saturated with couple stress fluid. The governing non-linear partial differential equations are transformed into a system of ordinary differential equations using similarity transformations and then solved numerically. Special cases of the present investigation are compared with previously published work and found to be in good agreement. Profiles of dimensionless velocity, temperature and concentration are shown graphically for different parameters entering into the analysis. Also the effects of the pertinent parameters on the rates of heat and mass transfer in terms of the local Nusselt and Sherwood numbers are discussed.
