Summary: Hybrid nanofluids have shown superior heat transfer performance in various applications, but further research is needed to explore their potential in a wider range of applications. This study analyzes the flow of a radiative magnetohydrodynamic (MHD) mixed convective alumina-copper/water hybrid nanofluid past an inclined shrinking plate. By applying similarity transformations, the flow model's partial differential equations are converted to ordinary differential equations (ODEs). The numerical solution is obtained using the fourth-order accuracy code (bvp4c) for the boundary value problem. The findings suggest that optimizing copper concentration, thermal radiation, and MHD effect can significantly enhance the heat transfer rate and prevent flow separation.

Summary: The present study investigates the thermophoretic diffusion and Brownian motion of Carreau-Yasuda nanofluid in a tube-like structure under peristaltic flow. The nonlinear radiation effect with heat and mass transfer is taken into account, along with dissipation, Joule heating, and heat source and sink effects. The governing mathematical problems are solved numerically, and non-dimensionalization is achieved using the lubrication approach and streamline functions. The study addresses various quantities including velocity, temperature, concentration, heat transfer rate, and trapping. The results demonstrate that increasing the Weissenberg number leads to higher velocity and larger trapped bolus, while increasing the temperature ratio parameter enhances the heat transfer rate.

Summary: In this study, a mathematical computational analysis was conducted on mixed convection nanofluid (CuO-water) flow in a lid-driven parallelogram enclosure with corrugated walls. The flow dynamics were investigated using the finite element method, and the outcomes in terms of isotherms, streamlines, and line graphs were analyzed against various emerging parameters. The results showed that at lower Richardson numbers, the flow exhibited forced convection, while at higher Richardson numbers, the flow transitioned to free convection. Additionally, maximum heat transfer was observed when a magnetic field was applied perpendicular to the flow and at maximum amplitude of wall undulations.

Summary: This article investigates the fluid flow and heat transfer characteristics of a nanofluid in both deep and shallow cavities. The study utilizes the Corcione model to consider various factors such as viscosity, conductivity, nanoparticle size, temperature, and Reynolds number. The simulation is conducted using the Navier-Stokes and energy equations in two dimensions, along with COMSOL 5.6 software. The results show that the temperature distribution in the cavity is circular, with the average temperature decreasing as the volume fraction of copper increases. However, both the Reynolds number and copper volume fraction enhance the average Nusselt number, indicating improved heat transfer along the cavity's middle line. The percentage change in the average Nusselt number decreases with increasing aspect ratio, indicating better conduction.

Summary: Owing to improved thermal efficiencies, hybrid nanomaterials find various applications in enhancing thermal impact and improving the efficiencies of solar collectors, thermal management systems and industrial processes. This research investigates the thermal impact of hybrid nanofluid with different nanoparticles on a porous infinite plate. Copper (Cu), aluminium oxide (Al2O3), and titanium oxide (TiO2) nanoparticles are characterized in interaction with a water base fluid, supported by thermal radiation phenomenon. The study considers a porous medium with uniform permeability in a flow regime, with a concentration equation considering the onset of chemical reaction. The closed form solution is obtained analytically, and thermal assessments are made for different parameters, comparing pure nanofluid with different nanoparticles.

Summary: The study found that the radius and magnetic field inclination of copper nanoparticles have a significant impact on the dynamics of chemical reactive water conveying the nanoparticles over an inclined surface. Numerical solutions revealed that inter-particle spacing increases viscosity, leading to a decrease in velocity, while an inclined magnetic field results in a higher temperature distribution. The rate of decrease in local skin friction coefficients is optimal when the magnetic field inclination angle is increased and the nanoparticle radius is large.

Summary: This study investigates the effects of unsteady Cattaneo-Christov double diffusion, random motion, and thermomigration of tiny particles on thermal storage and heat exchangers. It is found that thermal relaxation dependent on heat flux maximizes the temperature gradient, while thermal relaxation dependent on mass flux minimizes the concentration gradient. The choice of random motion provides a constant temperature gradient, while increasing thermomigration of tiny particles enhances the concentration gradient. Furthermore, the unsteady factor reduces the temperature and concentration distributions and condenses the boundary layer thicknesses.

Summary: The dynamics of blood carrying microscopic copper particles through overlapping stenotic arteries is an important research area, especially for understanding the flow dynamics in blood vessels. The study used the Casson model to analyze the peristaltic blood flow of copper nanoparticles in overlapping stenotic arteries. Higher temperature and velocity were observed in the stenosed arteries, with a decrease as it approaches the artery wall. The increase in the heat source parameter led to a higher temperature distribution.

Summary: Variability in temperature of stagnant and moveable wall is inevitable in the motion of water-based hybrid nanofluid subject to heat source on impermeable walls in the industry. However, little is known about the motion of water conveying spherical carbon nanotubes, cylindrical graphene, and platelet copper nanoparticles at different volumes of nanoparticles and levels of buoyancy. The governing equations are presented, non-dimensionalized, and numerically solved for constant pressure and asymptotically large Grashof number. It is worth concluding that minimal velocity is obtainable with stagnant impermeable surface, while minimal temperature distribution is obtainable with moving impermeable surface. Minimal local skin friction coefficients are obtainable with sufficiently large volume of nanoparticles (i.e., spherical carbon nanotubes, cylindrical graphene, and platelet copper) in water-based ternary-hybrid nanofluid flow on stagnant impermeable wall.

Summary: This study examines the dynamics of ethylene glycol conveying SWCNTs and MWCNTs nanoparticles under concentration and temperature stratification. It is found that thermal convective term affects the flow profile, velocity field, and thermal diffusion of SWCNTs and MWCNTs. Additionally, magnetic field-induced electromagnetic force and rising porosity decrease the characteristic flow dimension. Moreover, Ohmic magnetic dissipation positively influences SWCNTs and MWCNTs, while radiation has a negative influence. The Nusselt number shows an increasing trend for heat transfer in SWCNTs nanofluid, but a decreasing trend in MWCNTs nanofluid with higher volume fractions.

The non-linear partial differential equations are transformed into ordinary differential equations using local similarity transformations and numerically solved using MATLAB. The Tiwari-Das model is used to study the flow-thermal behavior of the nanofluid, and thermal conductivity formulations are incorporated based on experimental works. The investigation shows that the strength of homogeneous and heterogeneous reactions has opposite effects on the concentration fields.
