“…They also fined that the volume fraction has greater impact on temperature nanofluids. Acharya [9] and Gamachu and Ibrahim [10] analyzed the generalized non-Fick's and non-Fourier law for hybrid nanoliquid flow with entropy production over the rocket engine nozzle. A nanofluid over an inclined permeable rotating disk was described by Acharya [11] in terms of the flow pattern and temperature scenario.…”

Due to the synergetic effects of several types of nanomaterials, the primary goal of the hybrid nanofluid is to enhance the energy transport capabilities over a base fluid. Hybrid nanofluids have a wide range of applications in the industrial, technical, and medical industries, including solar heating systems, food processing, microchannel heat sinks (MCHS), and medicines. In this article, the researchers have investigated the water‐based hybrid nanofluid flow comprising silver and alumina nanoparticles past a spinning disk. The effect of Brownian motion, activation energy, magnetic field, and thermophoresis are taken into account. The PDEs are transformed into ODEs by means of suitable correspondence transformations. The modeled equations are solved by using a semi‐analytical method known as HAM. Graphical representations of the nanofluid and hybrid nanofluid profiles are used. The current findings are contrasted with those that have already been published and are confirmed to be remarkably comparable. The outcomes showed that the radial and tangential velocities of the nanofluids and hybrid nanofluid reduced as the magnetic factor augmented. Nanofluids and hybrid nanofluid surface drag is increased by magnetic factor. Hybrid nanofluid exhibits higher growth due to the magnetic factor than nanofluids do. The heat transmission rates of nanofluids and hybrid nanoliquid have grown as a result of the thermophoresis factor and nanoparticle volume fractions. In comparison to nanofluids, the hybrid nanofluid also possesses a better thermal conductivity.

“…2 The Yamada-Ota model and the Xue model were extended versions that were used to show the magnetohydrodynamic stationary point flow in hybrid nanofluid in Ishtiaq et al 3 In the temperature range of 5°C–55°C and under various laboratory settings, Esfe et al 4 examined the rheological behavior of a particular kind of hybrid nanofluid (HNF). Gamachu and Ibrahim 5 investigated the fluid flow, temperature, and entropy formation in a partially heated cavity saturated with porous media for buoyancy-driven flow of hybrid nanofluid. For various physical characteristics and surfaces, such as a moving plate, the investigation of numerical solutions in hybrid nanofluid flow was investigated, 6–12 cylinder, 13–17 disc, 18–23 and thin needle.…”

Several characteristics of the resulting fluid are influenced by the nanoparticle suspension. Understanding the heat transfer mechanism in nanofluids is necessary for many production and manufacturing applications. The current study examines the effects of mixed convection MHD and Joule heating on the flow of ( TiO2– GO/water) hybrid nanofluid and ( TiO2/water) nanofluids in the porous media between two parallel, infinitely spinning discs when radiation occurs. Using the “bvp4c” function in MATLAB, the governing equations are numerically solved. A graphic is used to show how important parameters affect the velocity, temperature, and concentration of nanoparticles. Finally, a table depicting the interactions between several important factors and skin friction, the Nusselt number, and the Sherwood number at the upper and lower discs is created. The findings show that while the local skin fraction drops with an increase in the mixed convection parameter, the heat transmission rate at both discs increases. Additionally, the rate of heat transmission at both the top and lower discs is reduced as the radiation and magnetic parameters increase. This study’s findings will be helpful to numerous nanofluid-based medicinal applications, architectural design systems, better oil recovery systems, and transportation procedures, among other sectors.

“…As part of their inquiry, it was shown that the magnetic field and the retorting parameter raised the nanofluid temperature while the Eckert number decreased for larger values. Furthermore, a variety of methods have been used to inquire the generalized Fourier's and Fick's laws of the fluid dynamics issues [19][20][21][22].…”

The present analysis focuses on a comprehensive study involving the synergistic exploration of diverse scientific concepts, encompassing micropolar trihybrid nanofluids, stagnation point flow, and second-grade fluids, with the use of expanded versions of the Fick's and Fourier's laws. Further, the influences of double stratification, viscous dissipation, activation energy, thermal radiation, and magnetohydrodynamics are incorporated. The research further extends to the implementation of the modified Fick's and Fourier’s laws, which provide a comprehensive framework for understanding heat-mass communication in such intricate systems. Using the proper similarity variables, the flow model equations are converted into their non-dimensional form. These transfer version equations are numerically resolved using MATLAB implementation of the BVP4C technique. For several emerging dimensionless parameters, the graphical and numerical results are derived and analysed. From the figures, clearly, with larger values of the 2nd -grade fluid parameters, the fluid velocity and temperature flow rapidly with the presence of ternary hybrid nanofluid in comparison to unary nanofluid.
