Summary: The thermal performance of energy conversion systems is crucial for efficiency improvement and depends heavily on the thermophysical features of the applied fluids. Increasing the volume fraction of solids can enhance thermal conductivity and dynamic viscosity, while the variation trend of specific heat depends on the base fluid. Higher temperature leads to increased thermal conductivity but decreased dynamic viscosity.

Summary: This study investigates the flow model of hybrid nanofluids (gold-silver/engine oil) over a stretched cylindrical surface and a sheet in a permeable medium. The novelty lies in considering surface-catalyzed reaction and homogeneous-heterogeneous reactions to accelerate chemical reactions. The heat transport phenomena are enhanced with the support of Joule heating, heat absorption/generation, and the convective heat boundary condition. Ordinary differential equations are obtained using boundary layer theory and numerically solved using the Keller box method. The results show that the thermal profile enhances while the velocity field reduces for different magnetic parameter estimates, and the fluid concentration decreases when the surface-catalyzed parameter increases.

Summary: Hybrid nanofluids have great potential for heat transport applications and exhibit better thermal stability and properties compared to standard nanofluids. This study investigates the injection of a mixture of methanol and silica-alumina nanoparticles into an electrically conductive disk with a permeable boundary. Results show that the presence of a magnetic field and the shrinking of the disk enhance the energy transport rate and wall stress, and the Hamilton-Crosser model exhibits better thermal conductivity.

Summary: In this study, nanofluids based on vegetal oil with different weight percentages of carbon nanotubes (CNT), hexagonal boron nitride (h-BN), and a hybrid of both (h-BN@CNT) were produced. The effects of these nano-additives on the thermal conductivity and rheological properties of the nanofluids were investigated. The results showed that the fluids produced with 0.5 wt.% of the hybrid nanomaterials exhibited an increase in thermal conductivity of up to 39%. Furthermore, it was found that the presence of CNT affected the rheological properties of the fluid, while h-BN changed the fluid's Newtonian behavior.

Summary: The study demonstrates that in PEM fuel cell applications, the 10:90 ratio of Al2O3-SiO2 hybrid can achieve optimal performance, with thermal and electrical conductivity decreasing as the percentage of Al2O3 increases, while viscosity performance exhibits the opposite trend. Considering the dominance of thermal properties over viscosity and electrical conductivity, the 10:90 ratio is the most suitable for implementation.

Summary: The study compares the Yamada-Ota and Xue thermal conductivity models for a mixed convective hybrid nanoliquid flow in a permeable vertical channel influenced by an induced magnetic field. The model considers thermal radiation, heat generation, and multiple slip conditions on the walls. The governing partial differential equations are transformed into ordinary differential equations using the similarity transformation and numerically solved using the bvp4c technique in MATLAB. The results are logically analyzed through illustrations and tables, showing that the induced magnetic field weakens the fluid velocity while an opposite trend is observed for higher Prandtl numbers.

Summary: This article presents a comparative study of magnetohydrodynamics stagnant point flow in hybrid nanofluid using the extended versions of the Yamada-Ota model and Xue model. The study considers a time-dependent and thermally radiative two-dimensional flow with a stretchable/shrinking permeable sheet. The hybrid nanofluid is formulated by suspending Aluminum Oxide Al2O3 and Copper Cu nanoparticles in water. The nonlinear dimensionless system of ordinary differential equations is solved numerically using the bvp4c methodology. The study finds that the heat transfer rate is higher in the Yamada-Ota model compared to the Xue model, and increasing the stretching parameter enhances the velocity field but deteriorates the temperature distribution.

Summary: In this study, temperature-dependent Yamada-Ota and Xue hybrid nanoliquid models were used to investigate the thermal performance over a curved stretchable surface embedded in an absorbent media. The results showed that the modified Fourier law combined with temperature-dependent thermal conductivity, Newtonian heating, and variable heat source/sink can enhance the thermal performance. Additionally, it was observed that the fluid velocity decreases with an increase in the velocity slip parameter and increases with an increase in the curvature parameter. Moreover, the temperature field is enhanced with the conjugate parameter. The results are in good agreement with the existing literature.
