Theoretical aspects of Brownian motion and thermophoresis on nonlinear convective flow of magneto Carreau nanofluid with Newtonian conditions

摘要

This article addresses magnetohydrodynamic (MHD) nonlinear convective stagnation point flow of Carreau nanofluid towards a stretching sheet with chemical reaction. Analysis is carried out in the presence of Newtonian conditions of heat and mass transfer. Brownian motion and thermophoresis phenomena have been utilized in energy and concentration expressions. Appropriate variables lead to development of nonlinear ordinary differential systems. Results for velocity, thermal field, nanoparticles concentration, skin friction and local Nusselt and Sherwood numbers are presented and investigated. Here higher values of material parameter corresponds to high velocity. Moreover the variations of temperature and nanoparticles concentration are opposite in frame of Brownian motion.
