Investigation of heat and mass transfer in an electromagnetically driven ionized tri-hybrid nanofluids flow over a convectively heated cylinder

Abstract

Nanofluids are employed in various heat transfer and cooling applications because of their enhanced thermal conductivity, making them useful for electronics cooling, solar collectors, and heat exchangers. The current study explores the behavior of a partially ionized Prandtl fluid with three types of nanoparticles as it flows through a convectively heated cylinder under magnetic influence. The purpose of dispersing three different nanoparticles $\left(\mathrm{MWCNT},A{l}_2{O}_3,\mathrm{SiC}\right)$ is to increase the functional fluid heat transfer rate. The study looks at how powerful produced magnetic and electric fields affect fluid flow under the supposition that the magnetic Reynolds number is very high. The study analyzes the mass and heat equations while taking into account factors like Joule heating, activation energy, varying thermal conductivity, and changing mass diffusivity. Additionally, the consequences of Joule heating, viscous dissipation, and thermal radiation are appraised when evaluating the disorder in the flow system through entropy generation. Based on these assumptions, differential equations were employed to create the mathematical model. The differential equations are then subjected to similarity variables to become a dimensionless variant of ordinary differential equations. The numerical scheme BVP4C on MATLAB has been used to find the numerical results. The comparison results are found for ternary nanofluid $\left(\mathrm{MWCNT},A{l}_2{O}_3,\mathrm{SiC}\right)$ and unary nanofluid $\left(A{l}_2{O}_3\right)$ using graphs. It is observed from the figures that in enhancement in Prandtl first parameter, curvature parameter, Hall and ion slip effect, the fluid motion enhances while the reverse behavior is observed for Hartman number. The fluid temperature surges with stronger estimations of the Dufour number, variable thermal conductivity, and radiation parameter.
