Abstract

A mathematical model of the steady boundary layer flow and heat transfer of nanofluid due to an exponentially shrinking sheetis investigated.Themodelusedfor thenanofluidincorporates the effectsofBrownianmotionandthermophoresis.The governing partial differential equations are transformed into ordinary differential equation by similarity transformations. The transformed equations are solved numerically by using shooting method. A similarity solution is presented which depends on the mass suction parameter S, Prandtl number Pr, Lewis number Le, Brownian motion Br and thermophoresis number Nt. It was found that the reduced Nusselt number is decreasing function of each dimensionless number.
