Abstract: In this study, we explore MHD flow of Carreau nanofluid towards stagnation point. Flow pattern is demonstrated via a mixed convective flow and Navier’s slip condition. Investigation has been done with the conditions of Newtonian heat and mass transfer. The principle of Brownian motion and thermophoresis are used for the representations of energy and concentration. The mathematical model is built using partial differential equations. Governing equations are converted by the process of similarity transformation into ordinary differential equations. The resulting equations are numerically solved using finite difference method. It is concluded that velocity profile increases for higher thermal buoyancy forces. The influence of various dimensionless parameters is analyzed for velocity, temperature and concentration profiles. The significant physical quantities such as skin friction coefficient, local Nusselt number and Sherwood number are presented for associated parameters. |
Keywords and phrases: stagnation point, Carreau nanofluid, thermophoresis, Brownian motion.
