Abstract


The effects of heat and mass stratification on mixed convection along a vertical plate embedded in a couple stress fluid has been presented. The nonlinear system of equations with appropriate boundary conditions are primarily reduced to non-dimensional form by pseudo-similarity transformations. Keller-box implicit finite difference scheme is employed to solve the resultant system of dimensionless equations. The validation of this scheme is shown through the comparison between the present and available literature under special case of the present problem. The couple stress parameter, mixed convection parameter and the double stratification parameter effects on the rates of heat and mass transfer for diverse values of the emerging flow parameters are illustrated in tabular form. The present results shows that the couple stress parameter, mixed convection parameter, thermal and the solutal stratification parameters influences the flow significantly.
