Abstract
In this article, the motion of a non-Newtonian tangent hyperbolic nanofluid past a stretching sheet is analyzed. Nanofluid is comprised of thermophoresis and Brownian motion effects. Magnetic field is implemented in vertical direction under the assumption of low magnetic Reynolds number. The phenomenon of heat transfer has been examined subject to the viscous dissipation and Joule heating whereas the mass transfer has been analyzed under the effect of chemical reaction. The partial differential equations (PDEs) governing the flow, heat and mass transport are re-framed in the form ordinary differential equations (ODEs) by means of the similarity solutions. A numerical procedure known as the Keller-box method has been implemented to obtain the solutions for the accomplished ODEs. The effects of the variations of different involved parameters on fluid temperature, velocity and concentration distributions are disclosed through graphs and analyzed in detail. The features of skin friction, heat and mass transfer coefficient are tabulated and graphed in order to perceive the flow, heat and mass transport processes. It is noticed that an increment in the Weissenberg number results in a reduction in the velocity field.

Summary
The flow behavior of non-Newtonian fluids has captivated the engineers and investigators in the past few decades in industrial sciences as well as in engineering. Among non-Newtonian fluid models, the tangent hyperbolic fluids model is capable of predicting the shear thinning (Pseudo-plastic) phenomenon. It is a type of fluids which determines the fluid resistance having dominant rate of shear stress. A number of researchers have already reported valuable analysis of the tangent hyperbolic fluid model keeping different flow phenomena. Ibrahim disclosed the magnetic effects on the slip flow of convectively heated and concentrated tangent hyperbolic nanoliquid over a stretchable surface. Kumar et al. described the variable thermal conductivity effects on squeezed tangent hyperbolic fluid flow past a sensor surface. Zakir and Gul investigated the thermal slip effect on tangent hyperbolic fluid flow over a stretching sheet
