Nanoparticle shape factor analysis on radiative ternary nanofluid (MWCNT-Cu-SiO2/H2O) flow with non-Fourier thermal flux

Abstract

The ternary hybrid nanofluid flow comprising multi-walled carbon nanotube, copper, and silicon dioxide dispersed in a host fluid of water in a Darcy-Forchheimer medium past an elongated surface is deliberated in the current study. The novelty of the contemplated model is developed by incorporating the influences of mixed convection in the momentum equation and heat source and Cattaneo-Christov thermal flux in the energy equation. Shape factor analysis of the nanoparticles is also performed to calculate the thermal efficacy. An application of the appropriate similarity variables is made to transmute the governing system of PDEs into an ordinary differential system, whose numeric solution is determined by the bvp4c package in MATLAB. The outcome drawn in this study is that the ternary hybrid nanofluid MWCNT-Cu-SiO2/H2O can provide effective thermal transmission efficiency compared to Cu-SiO2/H2O hybrid nanofluid. Additionally, the lamina-shaped nanoparticles seem to exhibit an improved thermal profile and greater heat transmission rate than platelets shaped ones. Moreover, a comparison table is included to authenticate the present model and a great correlation is attained.
