Effects of Nonlinear Thermal Radiation and Thermo-Diffusion on MHD Carreau Fluid Flow Past a Stretching Surface with Slip

Abstract:

The boundary layer flow of a heat transfer analysis on Carreau hydro magnetic fluid past a convectively nonlinear stretching surface analyzed. The nonlinear radiation, variable thermal conductivity and thermo diffusion effects are included in energy and species governing equations. The set of dimensionless integrated ordinary differential equations under the boundary restrictions obtained with the help of suitable similarity variable approach. The reduced governing flow equations with the boundary conditions are resolved numerically. Comparisons present results with existing literature and yields nice agreement .The description of results has been analyzed for the flow controlling embedded pertinent parameters by utilizing the plots and tables. It is revealed that energy distribution decays for enhancing values of variable thermal conductivity parameter whereas the opposite behavior to the thermal radiation parameter. The non-dimensional concentration boosts with the ascending values of Soret number.
