Nanoparticle analysis of non-Newtonian fluid with slip and multiple convective boundary conditions

Abstract

Slip flow of a Carreau nanofluid over a stretching sheet has been investigated. Thermophoresis and Brownian motion effects are taken into account. The Navier slip, thermal, and mass convective boundary conditions are taken into account. The prevailing partial differential equations are presented and transformed into a set of nonlinear ordinary differentials using scaling transformation. Effects of the physical parameters on velocity, temperature, and concentration profiles are computed numerically using the fourth-order Runge–Kutta–Fehlberg scheme. Numerical values of local Nusselt and Sherwood numbers are calculated and discussed. The obtained results revealed that enhancing the slip parameter consequently drops the temperature and concentration profiles. Heat and mass flux at the surface decreases with increasing thermophoresis parameter. Heat transfer rate enhances while the mass transfer rate decreases with the thermal Biot number.
