Radiation Effect on Boundary Layer Flow of a Nanofluid over a Nonlinearly Permeable Stretching Sheet

Abstract

We analyze the influence of thermal radiation on boundary layer flow of a nanofluid past a nonlinearly permeable stretching sheet. The governing partial differential equations are reduced into a system of ordinary differential equations using similarity transformation and then solved by using shooting technique. Effects of thermal radiation parameter, Brownian motion parameter, Suction parameter and Thermophoresis parameter on the flow, concentration and heat transfer characteristics are thoroughly investigated. The local Nusselt number and the local Sherwood numbers are presented and compared with existed results.
