Study of Carbon Nanotubes with a Casson Fluid in a Vertical Channel of Porous Media under MHD and Dufour Effect

Abstract

An analysis is conducted to investigate the problem of heat/mass transfer in MHD free convective flow of Casson-fluid in a vertical channel embedded with saturated porous medium past through carbon nanotubes in the form of single-wall carbon nanotubes (SWCNTs) and multiple-wall carbon nanotubes (MWCNTs) with engine oil as base fluid. In this article, the impact of CNT’s on velocity, temperature, shear stress and rate of heat transfer of the nanofluid has been investigated and studied graphically for the effects of different key physical parameters involved. The validity of this flow model is presented and is found satisfactory agreement with published results. The results state that, fluid velocity accelerates for greater values of Casson parameter and nanoparticles volume fraction, while thermal radiation (R) and heat generation (Q) assume a significant role in CNT's. Applications of this study arise in broad area of science and engineering such as thermal conductivity, energy storage, biomedical applications, air and water filtration, fibers and fabrics.

Analysis of Platelet Shape Al2O3 and TiO2 on Heat Generative Hydromagnetic Nanofluids for the Base Fluid C2H6O2 in a Vertical Channel of Porous Medium

“…The investigation on nanofluid with special emphasis on thermal radiation over a porous vertical cylinder is done by Kabeir et al [19]. [20,21] investigated the behaviour of CNT's in a vertical channel for human blood flow and Casson fluid. Hazarika et al [22] developed a numerical solution through finite difference scheme for the impact of thermophoresis and dissipating heat on hydromagnetic fluid over a stretching sheet in presence of nanoparticles Cu, Ag and Fe 3 O 4 .…”

Heat transfer analysis in a horizontal anisotropic porous channel with Bi-viscous Bingham nanofluid and temperature-dependent Brownian diffusion

“…Its unique rheological properties make it particularly suitable for these applications. Recently, Hazarika and Ahmed (2021) conducted a study on the flow of Bi-viscous Bingham fluid containing carbon nanotubes through a vertical porous channel. In their research, they investigated the behavior and characteristics of this fluid system.…”

Thermo-Diffusive Flow of Chemically Reacting Fluid in a Saturated Porous Medium for Radiative Heat Flux

“…Apart from these studies, investigators [27][28][29][30][31][32][33] had investigated analytically and numerically for the heat-mass transport in porous media due to the application of magnetic fluid with various configurations. Hazarika et al [34] has presented the analytical analysis of Cu-water nano-fluid of natural convection hydro-magnetic heat transport in a Darcian porous regime with diffusion-thermo.…”
