Brownian moment and thermophoresis effects on unsteady liquid film flow of MHD Carreau fluid over a stretching sheet

K.Avinash, R.Hemadri Reddy

Abstract

In this study, we analyzed the flow, heat and mass transfer nature of magnetohydrodynamic (MHD) steady/unsteady liquid film flow of Carreau fluid past a stretching sheet in the presence of thermophoresis and Brownian moment effects. Similarity transformation is used to convert the partial differential equations to nonlinear ordinary differential equations. Further, the transformed equations are solved numerically by employing bvp5c Matlab package. The effects of various controlling flow parameters on the flow, heat and mass transfer are examined and discussed in detail in steady and unsteady cases. It is found that flow, thermal and concentration boundary layers are non-uniform for steady and unsteady cases. Brownian moment and thermophoresis parameters regulate the heat and mass transfer rates.

Keywords
