Magnetohydrodynamic Flow of Nanofluid Over an Exponentially Stretching Sheet in Presence of Viscous Dissipation and Chemical Reaction

摘要

This frame work is devoted to studying the effects of viscous dissipation and chemical reaction on MHD flow of non-Newtonian nanofluid over an exponentially stretching surface with suction/injection. The system of partial differential equations is reduced to a system of non-linear ordinary differential equations by using suitable similarity transformations and solved numerically by Keller-Box Method. In the present study, the effects of the physical parameters on velocity, temperature and concentration profiles have been discussed and presented graphically. Also, the skin friction coefficient, local Nusselt and local Sherwood numbers at the sheet are exhibited and discussed. It is found that the thermal boundary layer thickness increases with increase in the viscous dissipation parameter. Finally, the concentration boundary layer thickness decreases with an increase in chemical reaction parameter.
