This correspondence, a three-dimensional radiative magnetohydrodynamic flow of hybrid nanofluid across an exponentially stretching surface is discussed. In this study we contemplate aluminium alloys of 7072 and 7072 + 7075 T6 type with transformer oil base liquid. AA7070 is composition of Zinc and aluminium in the ratio of 98 & 1 with supplementary metals Copper, Magnesium, Zinc and Aluminium in the proportion of, ~ 1, ~3, ~ 6, and ~ 90 correspondingly. AA 7075 is a composite of 90% Al, 5.5% Zn, 2.6% Mg, 0.24% Cr and 1.5% Cu. The density of these alloys’ mixture is 3.81 gm/cm3. It is one of the strongest aluminium alloys having reinforce process (heat treatment up to 300-500o C) to reconfigure any metal’s crystal structure to provide the mechanical deformation at low density than others metal alloys. These alloys mixture found some applications in Missile parts making, Aerospace system, Défense, Aircraft designing and fittings, Steel worm gears and in many others discipline. These alloy mixtures are treated in conventional fluid to enhance the heat transfer characteristics of nanofluid. Flow is induced by Cattaneo-Christov heat mass flux model perception. The solutions of reduced dimensionless nonlinear ordinary differential equations are handled through Mathematica built-in ND Solve scheme. Significant role of several physical parameters govern by the equation of motions are discussed through plots. Comparisons with the previously published article also validate the efficiency of the technique as well. Results, shows that the heat transfer rate of the AA7072/ AA7075 hybrid nanofluid is remarkably enormous as compared with the usual nanofluid.

“…These models amalgamate elements from two or more of the aforementioned models to encapsulate the distinctive characteristics of nanofluids. As an illustration, a hybrid model that combines features from both two-phase and three-phase models can be employed to investigate phenomena such as nanoparticle deposition and suspension behavior within a nanofluid system [5].…”

This study focuses on modeling of Al 2 O 3 -water nanofluids energy transport in a microchannel using multiphase Eulerian model. The study of the Knudsen number showed that continuum can be assumed above volume fraction 2.5%. Therefore, conservation equations can be used to solve both phases separately. In addition to conservation equation, an effort has been made to model fluid-solid interaction, solid-solid interaction, and interphase heat transfer. Various phenomenon such as shear viscosity, bulk viscosity, granular temperature, wall lubrication forces, virtual mass forces, lift, and drag forces are modelled. Moreover, interphase heat transfer is modelled. Finally, this comprehensive model is used to study heat transfer enhancement of Al 2 O 3 -water nanofluids with volume fraction of 3%, 4%, 5%, and 6%. It is found that the heat transfer increases with increase in volume fraction of the solid phase in the range considered in this study. The comparison of the average heat transfer coefficient of water with Al 2 O 3 -water nanofluids showed that heat transfer coefficient enhancement of 9.

“…The research reveals that the velocity profile decreases as the magnetic field grows as well as the slip parameter and electric field increase. Using fuzzy volume fraction, Verma et al [7] investigated the impact of heat transfer on hybrid nanofluid flow in converging/ diverging channels. This work uses hybrid nanoparticles, Cu and Cu-Al 2 O 3 , to investigate the magnetohydrodynamic (MHD) Jeffery-Hamel nanofluid flow between two stiff non-parallel plane walls with heat transmission.…”

Solar energy is the most important heat source from the sun, with photovoltaic cells, solar power plates, photovoltaic lights, and solar pumping water being widely used. This study looks at solar energy analysis and a method for increasing the efficacy of solar aircraft by combining solar and nano-technological energy. To enrich the research on solar aircraft wings, the study is built on the investigation of heat transfer by employing a hybrid nano-fluid past inside the parabolic trough solar collector (PTSC). The thermal source is referred to as the solar radiative flow. The heat transfer efficiency of the wings was validated for different qualities such as porous medium, viscous dissipation, play heating, and thermal energy flow. The modelled energy and momentum equations were controlled by utilizing the Galerkin-weighted residual method (GWRM). This study used two types of nano-solid particles, copper (Cu) and zirconium dioxide (ZrO2), in ethylene glycol (EG) as the standard fluid. Various control parameters for velocity, temperature outlines, frictional factor, and Nusselt number were explained and shown in figures and tables. Also, analyses reveal that the thermal profile reduces with an increase in variable thermal conductivity parameters. This study will be of considerable economic value to marine engineers, mechanical engineers, physicists, chemical engineers, and others since its application will help them improve their operations. The findings revealed that the magnetic term is positively impacted by the Cu-ZrO2/EG hybrid nanofluid's thermal distribution.
