Comparative Analysis of Darcy–Forchheimer Radiative Flow of a Water-Based Al2O3-Ag/TiO2 Hybrid Nanofluid over a Riga Plate with Heat Sink/Source

Abstract

The behavior of the Darcy–Forchheimer flow of a double-hybrid nanofluid toward a Riga plate with radiation and heat source/sink effects is investigated. The two different hybrid nanofluids, (Al2O3 and Ag) and (Al2O3 and TiO2) with a base fluid (H2O), are considered. The governing flow models with accompanying boundary constraints are reshaped into non-linear ODEs by applying the symmetry variables. The reshaped ODEs are numerically computed using Bvp4c in Matlab and the ND solver in Mathematica. The impact of the emerging parameters on the heat transfer, surface shear stress, temperature and velocity profile is scrutinized and expressed in a tabular and graphical structure. It is noticed that the upsurge of the Hartmann number leads to an improvement in the velocity profile. The velocity declines when enriching the porosity parameter. The radiation and Biot number lead to strengthening the temperature profile. The surface shear stress exalts due to a larger modified Hartman number. The radiation and unsteady parameters are downturns in the heat transfer gradient.

Melting Heat Transfer Rheology in Bioconvection Cross Nanofluid Flow Confined by a Symmetrical Cylindrical Channel with Thermal Conductivity and Swimming Microbes

“…Heat transfer analysis in non-Newtonian fluids is more important in applications such as drug delivery or heat optimization [38,39]. This concept is also of more interest in the case of nanofluids/hybrid nanofluids for enhancing the heat transfer rate of traditional fluids [40,41].…”

Magnetohydrodynamic bioconvective flow past an elongated surface with convective heat transport, and velocity slip in a non‐Darcian porous regime

“…To get to know how radiation affects MHD-free convective mass transport in viscous flow across a stretchy surface, Nalivela et al 37 conducted investigations. The motion of CNTs based on water and kerosene across a Riga surface under convective heating and radiation circumstances was explained by Prabakaran et al, 38 Rajupillai et al, 39 Alessa et al, 40 Sindhu et al, 41 Kayikci et al, 42 Sajid et al, [43][44][45] Fangfang et al, 46 and Senthilvadivu et al 47 studied the thermal radiation effects for different aspects.…”
