The primary heat source from the sunlight is solar energy, which is used in photovoltaic panels, solar power plates, photovoltaic streetlights, and solar-based hybrid nanocomposites. A hybrid nanofluid is traversing an expanding sheet in this investigation. Maxwell fluid stream with two nanoparticles is going towards a trough with a parabolic form and is situated within the solar aircraft wing to investigate the phenomena of heat transfer rate. The term solar thermal radiation was introduced to describe heat transfer occurrence. The effectiveness of heat transmission from airplane wings is assessed by taking into account unique phenomena such as magnetic field and heat source. The bvp4c procedure was applied to quantitatively explain the energy and motion equations with MATLAB software. The copper (Cu) and graphene oxide (GO) nanosolid particles are mixed with sodium alginate (SA), a common liquid, to form the nanosolid particles. Numerous control variables are thoroughly examined, including temperature, shear stress, motion, friction component, and Nusselt number. The skin-friction coefficient upsurges with a growing magnetic impression. The upsurge in Deborah number reduces the skin-friction coefficient. The heat source impression declines the heat transport rate but upsurges the skin-friction coefficient. The skin-friction coefficient and heat transport rate increase with growing magnetic impression. When it comes to heat transfer analysis, hybrid nanofluid efficiency is substantially superior to that of regular nanofluid.

The present work examines the impressions of radiation impact on the three-dimensional non-Newtonian MHD Casson flow of ternary hybrid nanofluids over a symmetrical stretching sheet with magnetic impression and heat generation/absorption. The unique boost in thermal efficiency and development of the rate of heat transport as valid to the dynamics of energy and coolant in automobiles is what has led to an increase in knowledge of hybrid nanofluid. For the study, two groups of ternary nanoparticles (CNT-Gr-Fe₃O₄ and MgO-Cu-Au) are combined with the base fluid kerosene oil. A nonlinear partial differential equation system is created while keeping in mind some reasonable presumptions. Using the similarities transformation, PDE’s are changed into nonlinear ODE’s. Also, it is then mathematically simplified with the bvp4c technique. The consequences of an exclusive group of unique impacts on motion characteristics, skin friction coefficient, thermal field impressions, heat transport rate, concentration distribution, and mass transfer rate are described clearly. The motion in the x and y directions decays with increasing the Casson fluid parameter and magnetic impact for ternary groups I and II. An energy upsurge profile appears for radiation impression (1 Nr 20) and heat source/sink (0.1 Q 1.5). When compared to rising Dufour number (0.1 Du 0.9) and heat source/sink values (0.1 Q 1.5), the Nusselt number decreases. The volume fraction of ternary nanoparticles rises the velocity (in both directions) and thermal distributions. Also, the Nusselt number enhances for both ternary groups when increasing thermal radiation (1 Nr 20).

In the existing work, we have discussed the conclusion of Joule heating on incompressible (density is constant), radiative, chemically reacting and electrically conducted visco-elastic time-dependent fluid flow, heat & mass transpose via a media with pores between standing equidistantly dishes with persistent of slip state also with suction in existence of inclined magnetic field. In motion equivalence Lorentz force and in temperature equivalence Joule heating effect is considered. The electro-magneto force offered is too minor, because we supposed that the fluid has small electric conductivity. A magneto field is embedded in inclined track of the plates. By using regular perturbation technique, the oscillating unsteady coupled Navier-Stoke’s equations are answered for the fluid motion, temperature and volume fraction profiles. The influence of numerous physical dimensionless quantities on fluid motion, temperature, volume fraction, coefficient of skin friction (C_f), Nusselt number (Nu) and Sherwood number (Sh) at the dishes are acquired, deliberated mathematically and exposed via diagrams.

Viscous incompressible fluid flow in the middle of two co-axial infinite rotating porous discs is being investigated. Here flow is considered time dependent. Also, fluid is being injected through lower disc which is considered for equal to rate of suction of fluid through upper disc. The discs are rotating in the planes z = 0 and z = d (t), where L and have dimensions of length and t-1, respectively and t is the time. Different angular velocities are being taken for both the discs. It is also assumed that the lower disc is isothermal. Heat transfer analysis is also being carried out in the study. Mathematical model of the problem is being solved using perturbation method to get exact solution of the problem. Results are depicted with the help of graphs and tables for fluid flow velocities as well as for temperature.
