Nowadays external magnetic fields are capable of setting the thermal and physical properties of magnetic-nanofluids and regulate the flow and heat transfer characteristics. The strength of the applied magnetic field affects the thermal conductivity of magnetic nanofluids and makes it aeolotropic. With this incentive, we investigate the flow and heat transfer of electrically conducting liquid film flow of Carreau nanofluid over a stretching sheet by considering the aligned magnetic field in the presence of space and temperature dependent heat source/sink and viscous dissipation. For this study, we considered kerosene as the base fluid embedded with the silver (Ag) and copper (Cu) nanoparticles. Numerical results are determined by employing Runge-Kutta and Newton's methods. Graphs are exhibited and explained for various parameters of interest. The influence of pertinent parameters on reduced Nusselt number, flow and heat transfer is discussed with the assistance of graphs and tables. It is found that thermal boundary layer of Ag-kerosene nanofluid is highly effective when compared with the Cu-kerosene nanofluid. It is also found that the thermal and momentum boundary layers of Cu-kerosene and Ag-kerosene nanofluids are not uniform.

“…Using the homotopyperturbation method (HAM). Khan et al [14] analysed the effects of variable viscosity and thermal conductivity on the flow and heat transfer in a laminar liquid film over horizontal stretching sheet. Lin et al [15] studied MHD pseudo-plastic nanofluid unsteady flow and heat transfer in a finite thin film over stretching surface with internal heat generation and he observed that as the power law index increases, unsteadiness parameter and the critical value increase, while velocity and the temperature profiles and nanofluid films decrease.Cortell [16], Afzal [17], VajraVelu [18] analyzed the effects of various parameters governing the flow of viscous fluid over a non-linearly stretching sheet.…”

Abstract-This paper deals with radiation consequences on stagnation point flow with a non-linearly stretching sheet in a porous media immersed in a ethylene glycol based nanofluid. We also studied the issue of magneto hydrodynamic (MHD) flow of a viscous fluid done with a non-linear stretching sheet in a porous media. Various ethylene glycol based nanoparticles Copper(Cu), Alumina(Al 2 O 3 ), and Silver(Ag) are taken into consideration.

“…It has been shown by many authors that this method provides improvements to the existing numerical techniques. Considerable research [23][24][25][26][27][28][29][30] has been recently conducted on applying this method to a wide class of linear and nonlinear equations. However, to the best of the author's knowledge, no one has studied the MHD ow of a linear visco-elastic uid above a shrinking/stretching sheet by means of homotopy perturbation method.…”

KEYWORDSAbstract. In this paper, a series solution is obtained for MHD ow of linear viscoelastic uid over a shrinking/stretching sheet by using Homotopy Perturbation Method (HPM). The governing Navier-Stokes equations of the ow are transformed to an ordinary di erential equation by a suitable similarity transformation and stream function. The in uence of various parameters such as Hartman number and Deborah number on the velocity eld is analyzed by appropriate graphs. Finally, the validity of results is veri ed by comparing them with numerical results. Results are presented graphically and in tabulated forms to study the e ciency and accuracy of the homotopy perturbation method.
