Abstract
Here impacts of Joule heating and nonlinear radiation in mixed convective flow of Walter-B liquid are addressed. Buongiorno model related with Brownian motion and thermophoretic diffusion is employed. Thermal and solutal convective conditions are implemented at the boundary. The modeled equations are reduced into dimensionless quantities. The governing mathematical problems are tackled via homotopic procedure. Consequences of physical constraints are expressed through the plots. Thermal field is declared increasing function of temperature ratio and thermal radiation factors. Moreover larger Schmidt number yields lower nanoparticle concentration. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
