“…Asymptotic boundary layer solutions are presented for the combined convection from a vertical semi-infinite plate to a micropolar fluid by Gorla et al (1990). Wang (1998) examined the effect of wall conduction on laminar mixed convection heat transfer of micropolar fluids along a vertical flat plate. Chang and Lee (2008) analysed flow and heat transfer characteristics of the free convection on a vertical plate with uniform and constant heat flux in a thermally stratified micropolar fluid.…”

The effects of thermal and solutal stratification on mixed convection along a vertical plate embedded in a micropolar fluid saturated non-Darcy porous medium are analysed. The nonlinear governing equations and their associated boundary conditions are initially cast into dimensionless forms 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 velocity, microrotation, temperature and concentration profiles are shown for different values of the coupling number, non-Darcy parameter, mixed convection parameter, thermal and solutal stratification parameters. The numerical values of the skin friction, wall couple stress, heat and mass transfer rates for different values of governing parameters are also tabulated.

“…Na [5] investigated the effect of wall conduction on the heat transfer characteristics of the natural convection over a vertical slender hollow circular cylinder. Wang [6] studied the thermo-fluid-dynamic field resulting from the coupling of wall conduction with laminar mixed convection heat transfer of micropolar fluids along a vertical flat plate. Pop et al [7] presented a detailed numerical study of the conjugate mixed convection flow along a vertical flat plate.…”

“…The heat and mass transfer in micropolar fluids is also important in the context of chemical engineering, aerospace engineering and also industrial manufacturing processes. The problem of mixed convection heat and mass transfer in the boundary layer flow along a vertical surface submerged in a micropolar fluid has been studied by a number of investigators [3][4][5][6][7].…”
