A numerical study of electro-osmosis Williamson nanofluid flow in a permeable tapered channel

Abstract

This paper aims to analyze the mathematical and theoretical scrutiny of non-Newtonian Williamson liquid on an asymmetry tapered channel with thermal and mass transportation. No slip boundary conditions for velocity, heat and concentration are kept on channel walls. Buongiorno model for thermal transport of nano-fluid is also incorporated. Flow in permeable surface is categorized via modified Darcy law. Current problem is formulated by incorporating distinct effects such as modified Darcy law, electro osmosis, heat generation and chemical reaction. RK-4 based shooting method has been utilized to evaluate the nonlinear equations. Graphical results are formulated to visualize the prominence of distinct parameters.
