In this analysis, the thermal and flow properties of modified hybrid nanofluids (MNFs) have been investigated under the effects of electroosmosis and homogeneous-heterogeneous chemical reactions. Three types of nanoparticles of Cu, CuO, and Al2O3 are utilized to monitor the performance of the MNFs with water as a working liquid. The determination of the heating phenomenon is explored by incorporating the effects of NPs shape, temperature reliant viscosity, Joule heating, heat generation/absorption and viscous dissipation. In this exploration, equal diffusion factors for the auto catalyst and reactants are assumed. The model formulation contains a highly non-linear PDE system, which is converted to ODEs under physical assumptions with lubrication and Debye–Huckel. The solution treatment involves the Homotopy perturbation method for solving the governing differential equations is used. A major outcome discloses that an addition in heterogeneous reaction parameter aids in enhancing the concentration profile. In a result, the temperature curve decreases at increasing volume fraction of the NPs. Modified hybrid NFs have higher heat transfer rate as compared to base H20, or ordinary Al2O3–H20 and hybrid Cu + Al2O3–H20 NFs. Pressure gradient decreases by improving electroosmotic parameter. Further a comparison between analytically (HPM) and numerical results (NDSolve) show that both results are in good agreement.

Lately, a new class of nanofluids, namely hybrid nanofluids, has been introduced that performs much better compared with the nanofluids when a healthier heat transfer rate is the objective of the study. Heading in the same direction, the present investigation accentuates the unsteady hybrid nanofluid flow involving CuO, Al2O3/C2H6O2 achieved by an oscillating disk immersed in the porous media. In a study of the homogeneous and heterogeneous reactions, the surface catalyzed reaction was also considered to minimize the reaction time. The shape factors of the nanoparticles were also taken into account, as these play a vital role in assessing the thermal conductivity and heat transfer rate of the system. The assumed model is presented mathematically in the form of partial differential equations. The system is transformed by invoking special similarity transformations. The Keller Box scheme was used to obtain numerical and graphical results. It is inferred that the blade-shaped nanoparticles have the best thermal conductivity that boosts the heat transfer efficiency. The oscillation and surface-catalyzed chemical reactions have opposite impacts on the concentration profile. This analysis also includes a comparison of the proposed model with a published result in a limiting case to check the authenticity of the presented model.

In this modern era, the thermal efficiency of susceptible systems is a major concern in many scientific and technical operations. Hybridized nanomaterials have innovative behaviours, which make them significant in various applications. Hybrid nanofluids (HNFs) are primarily utilized to address heat transfer concerns efficiently. Keeping view of these facts, the main motive of the current investigation is to address the critical role of magnetohydrodynamics with Hall currents on a time-dependent gyrating stream of non-Newtonian modified hybrid nanofluid (MHNF) with Casson fluid model past a vertically fluctuating plate with ramped motion, and Newtonian heating in a porous environment. As a counter-example to Casson fluid, sodium alginate (SA) is considered. Graphite oxide, alumina and copper oxide nanoparticles are dispersed in the host fluid (SA) to constitute a MHNF. Thermal transportation is analysed under the physical consequence of thermal radiation. Darcy's law is utilized to counterfeit the porous medium's resistance in the flow field. The modelled problem is initially expressed in terms of physical conditions and partial differential equations (PDEs). The resulting dimensionless PDEs are solved analytically by dint of the Laplace transform technique. The physical consequences of significant physical and geometrical parameters on the profiles of associated flow quantities of industrial concern are visualized and explained in-deep via several graphs and tables. Our simulation reveals that the fluid motion is noteworthy amended due to the existence of Coriolis and Lorentz forces with Hall currents. Hall currents and Darcian drag force have a dominating attribute on the primary shear stress, while they expose a positive response to the secondary shear stress. Comparative analysis suggests that the heat migration rate at the plate is superior for MHNF due to higher thermal conductivity than usual HNF. The ongoing research is relevant to hybrid nanolubricants in thermal management systems, dynamics of nanopolymers, industrial procedures and so forth.
