Effect of momentum slip on double-diffusive free convective boundary layer flow of a nanofluid past a convectively heated vertical plate

摘要

The Buongiorno and Darcy models have been used to investigate the effects of momentum slip on the double-diffusive free convective flow past a convectively heated vertical plate in a medium saturated with nanofluids. The vertical plate has uniform surface temperature, solutal and nanoparticle concentrations. The governing transport equations are transformed into four nonlinear, coupled similarity equations using similarity transformations developed by scaling group transformation, and are solved numerically to obtain the dimensionless functions in the respective boundary layers and the dimensionless heat and mass transfer rates. The solution depends on various dimensionless numbers, and nanofluid, double-diffusion and slip parameters. The results of the present paper show that the flow velocity, temperature, nanoparticle concentration, reduced local Nusselt and reduced Sherwood numbers are strongly influenced by the hydrody-namic slip parameter.
