Thermal radiation influence on non-Newtonian nanofluid flow along a stretchable surface with Newton boundary condition

Abstract

This article focuses on the heat transfer on a mixed convection flow of nanoparticles suspended non-Newtonian nanofluid past a stretching surface under Newtonian boundary conditions. The leading boundary layer equations are changed to a non-linear boundary value problem by using suitable similarity variables. BVP4c with MATLAB is used to elucidate the resultant system. The controlled parameters involved in the flow field problem and its impact on the flow components as well as the interested engineering quantities are examined via graphs and tables. Our study results are in good agreement with the existing literature. It is noticed that the presence of radiation increases the heat inside the fluid, which leads to an increase in the thickness of the energy boundary layer and an increase in the temperature of the fluid. The temperature of the fluid decreases for higher values of the Brownian motion parameter and increases for variations in thermophoresis.
