Impact of Hall Current on Chemically Reactive Darcy Forchheimer Flow of Hybrid Nanofluid Over Moving Slender Needle

A numerical investigation of steady chemically reactive MHD hybrid nanofluid flow over a moving slender needle is presented in this study. The flow is considered in a porous medium incorporating inertial effects. The hybrid nanofluid comprises of Al2O3 and Cu nanoparticles with H2O as base fluid. The flow is governed by conservation of mass, energy and momentum as well as the concentration equation which are reconstructed using suitable similarity transformation. The Keller Box finite difference scheme, which is implicit, is employed to perform the numerical computations. The effects of various physical parameters, such as the Forchheimer number, Hall current, chemical reaction on velocity, concentration, and temperature profiles are illustrated graphically. The outcomes of this study are beneficial for enhanced understanding of flow over slender needle configuration. The findings are compared with existing literature to validate the numerical scheme.
