Computational analysis of the unsteady 3D chemically reacting MHD flow with the properties of temperature dependent transpose suspended Maxwell nanofluid

Abstract

The current research explores an unsteady three-dimensional Maxwell nanofluid flow with variable viscosity and thermal conductivity through a stretching surface. The influence of Joule heating, heat generation/absorption, and chemical reaction are also incorporated in current investigation. By the utilization of suitable transformation, the flow model is transformed into coupled ordinary differential equations. The numerical solution of the coupled ODEs is adopted by the usage of Bvp4c built-in code in MATLAB software. The graphical findings are manipulated to present the features of heat and mass transfer for the different parameters. It is observed form the graphical description that the velocity of fluid declines for stronger estimation of Deborah number, because it provides resistance to fluid motion. Further, enhancement is arisen in the velocity of fluid by the increment of the variable viscosity parameter. It is examined from the tabulated data, that the Nusselt and Shewrood number displays reducing behavior for the unsteadiness parameter. Moreover, due to higher estimation of variable thermal conductivity parameter the heat transfer rate declines consequently.
