Modified thermal and solutal fluxes through convective flow of Reiner-Rivlin material

Heat transport in mixed convection Reiner-Rivlin liquid flow due to stretching cylinder is addressed. CattaneoChristov double diffusive relation is utilized to discuss heat and solutal transport features. Variable thermal conductivity and mass diffusivity impacts are incorporated. Adequate transformations are used to reduce nonlinear differential expressions for dimensionless expressions. The given non-dimensional expressions are solved through implementation of Optimal homotopy analysis technique (OHAM). Physical features of fluid flow, concentration and temperature against influential parameters are examined. Clearly higher mixed convection parameter boost the liquid flow. Decay in temperature is detected against thermal relaxation time. Similar impact of temperature is witnessed by curvature and thermal conductivity variables. Velocity enhances against ReinerRivlin material variable. Decline in concentration is detected for higher Schmidt number. Concentration boosts against mass diffusivity parameter. Higher solutal relaxation time parameter leads to decline concentration. Reduction in temperature is noticed for Prandtl number whereas opposite behavior witnessed for heat transport rate. An increment in mass transport rate occurs for mass diffusivity and solutal relaxation time variables.
