A finite thin film flow of pseudo-plastic MHD hybrid nanofluid with heat generation and variable thermal conductivity

The primary objective of this article is to get an overview of electrically conductive pseudo-plastic hybrid-nanofluid in a finite thin film over an unsteady, nonlinearly stretching surface. Viscous dissipation, internal heat generation, magnetohydrodynamics, and the temperature-dependent thermal conductivity effects are examined while examining the flow velocity and temperature of the fluid. Different types of hybrid-nanoparticles are assessed, which are the amalgam of Cu, TiO2, CuO, and Al2O3 with Carboxy-methyl Cellulose (CMC)-water as base fluid. Further, modified heat conduction of Fourier's law concerning the power-law model is utilized instead of a classical model. The resolved partial differential equations (PDEs) are transformed into a couple of non-linear ordinary differential equations (ODEs) after using specified transformations. Runge–Kutta technique of order four coupled with shooting method is applied to acquire the numerical solutions. The effects on velocity and temperature profiles due to the behavior of power-law-index, Hartmann number, Prandtl number, and unsteadiness parameter are analyzed and graphically presented. It is observed that TiO2 and CuO hybrid nanofluid has the most influential impacts on the Nusselt number as compared to the other three combinations. The temperature gets a decline with the increasing power-law index.
