Abstract

The present investigation provides an insight in the steady, incompressible and electrically conducting boundary layer flow of viscoelastic nanofluid flowing due to a moving, linearly stretched surface. The governing system of nonlinear partial differential equations is simplified by considering Boussinesq and boundary layer approximations. An analytical solution of the resulting nonlinear ordinary differential equations for momentum, energy and concentration profiles is obtained using the homotopy analysis method (HAM).

Highlights

Enhancement of thermal conductivity in the base fluid due to the presence of nano sized solid particles is studied vigorously by different researchers in the recent past
Khan et al [3] have deliberated the effects of thermal radiation, heat generation and chemical readtion over the magnetohydrodynamic laminar boundary layer flow of a nanofluid past a wedge
Nadeem and Rehman [4] have presented an analytical solution for the finite radial domain, axisymmetric stagnation flow of a nanofluid flowing between the annular region formed by two concentric cylinders, when the inner cylinder is translating along and rotating about the axial direction with constant linear and angular velocities

Summary

Introduction

Enhancement of thermal conductivity in the base fluid due to the presence of nano sized solid particles is studied vigorously by different researchers in the recent past. Khan et al [3] have deliberated the effects of thermal radiation, heat generation and chemical readtion over the magnetohydrodynamic laminar boundary layer flow of a nanofluid past a wedge. Khan et al [7] have analyzed the time dependent boundary layer flow of nanofluid flowing along a stretced surface and is under the influence of a magnetic field with viscous dissipation and thermal radiation. They [7] observed that the boundary layer concentration of nanoparticles is highly dependent upon their size and shape. Few other motivating studies about the flow behavior of nanofluids are cited in [8,9,10,11,12,13]
