Radiative MHD Nanofluid Flow over a Moving Thin Needle with Entropy Generation in a Porous Medium with Dust Particles and Hall Current

Abstract

This paper investigated the behavior of the two-dimensional magnetohydrodynamics (MHD) nanofluid flow of water-based suspended carbon nanotubes (CNTs) with entropy generation and nonlinear thermal radiation in a Darcy-Forchheimer porous medium over a moving horizontal thin needle. The study also incorporated the effects of Hall current, magnetohydrodynamics, and viscous dissipation on dust particles. The said flow model was described using high order partial differential equations. An appropriate set of transformations was used to reduce the order of these equations. The reduced system was then solved by using a MATLAB tool bvp4c. The results obtained were compared with the existing literature, and excellent harmony was achieved in this regard. The results were presented using graphs and tables with coherent discussion. It was comprehended that Hall current parameter intensified the velocity profiles for both CNTs. Furthermore, it was perceived that the Bejan number boosted for higher values of Darcy-Forchheimer number.

Impact of hall and ion slip in a thermally stratified nanofluid flow comprising Cu and Al2O3 nanoparticles with nonuniform source/sink

“…The numerical solution of the flow of magnetized partially ionized fluid with an amalgamation of nano-sized particles considering the effects of non-uniform heat source, thermal radiations, and heterogeneous homogeneous reactions, is investigated by Nawaz et al 39 . Some recent studies highlighting the impacts of Hall current may be found in [40][41][42][43][44] .…”

Entropy Generation Analysis of Hybrid Nanomaterial through Porous Space with Variable Characteristics

“…Latest developments in flow through a porous medium with constant porosity and permeability and can be cited through refs. [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. However little information is available for variable characteristics of porous space [ 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]…”
