Abstract

The aim of this article to inspect the effect of nonlinear thermal radiation, heat joule, viscous dissipation and magnetic field on viscoelastic second grade fluid. Flow is generated due to stretching of sheet. Flow features are studied considering hydrodynamic boundary conditions. Chemical reaction on the surface is further accounted. The flow governing nonlinear partial system of differential equations is obtained incorporating boundary layer assumptions. The dimensional model is made dimensionless by taking suitable transformations and then tackled via HAM for convergent series solution. Effects of flow controlling parameters on velocity, concentration, temperature, local skin friction coefficient, Sherwood number and Nusselt numbers are discussed by plotting graphs. Main observations are listed at the end.

Highlights

  • Magnetohydrodynamics(MHD) is a part of science which describes the relation between the magnetic fields and moving electrically conducting fluid

  • The flow field study near stretching sheet in boundary layer flow is an important process in fluid dynamics and engineering

  • The heat transfer process occurring in different engineering processes such as crystal growth, plastic sheets, glass fiber, polymer processing and metallurgy [10]

Summary

Introduction

Magnetohydrodynamics(MHD) is a part of science which describes the relation between the magnetic fields and moving electrically conducting fluid. Hydromantic phenomenon becomes more important due to its practical applications in engineering, physics chemistry and industries, like MHD throttles, automatic fuel level indicator, nuclear reactor, magnetometer, electronic motors and transformer. Analytical and numerical solution of MHD boundary layer flow problem over an unsteady stretching sheet is reported by Sheikholeslami [9]. The flow field study near stretching sheet in boundary layer flow is an important process in fluid dynamics and engineering. Ghosh et al [11] applied Laplace transformation to study the behavior of flow of MHD viscoelastic incompressible fluid having small particles and moving between two parallel plates of infinite length. To investigate heat transfer in MHD viscoelastic fluid flow in presence of thermal radiation over a semi-infinite, non-isothermal stretching impermeable sheet with internal heat generation/ absorption, Datti et al [12] applied fourth-order RK-4 (Runge-Kutta-4) method
