ABSTRACT

In this paper, double-stratification effects on mixed convection heat and mass transfer along a vertical plate embedded in a couple stress fluid with flux distributions has been studied. The nonlinear governing equations and their associated boundary conditions are initially cast into dimensionless form by pseudo-similarity variables. The resulting system of equations is then solved numerically using the Keller box method. The numerical results are compared and found to be in good agreement with previously published results as special cases of the present investigation. The effects of couple stress parameter, mixed convection parameter, and double-stratification parameters on heat and mass transfer rates for different values of governing parameters are tabulated. An analysis of the results obtained shows that the flow field is influenced appreciably by emerging parameters of the present study.
