Summary: This paper investigates the MHD stagnation-point flow of Cu-Al2O3/H2O hybrid nanofluid on a convectively heated shrinking disk, taking into account suction, Joule heating, and viscous dissipation effects. Numerical solutions reveal the existence of two solutions, with the first solution being physically stable. The results show that an increase in suction and magnetic parameters enhances the heat transfer performance, while the Eckert and Biot numbers have no effect on the critical value. The temperature profile decreases with an increase in the velocity ratio parameter, Eckert and Biot numbers, while the velocity increases with an increase in the velocity ratio and magnetic parameters.

Summary: This study numerically analyzes the impact of an inclined magnetic field and Joule heating on the conjugate heat transfer of Al2O3-water nanofluid in a thick wall enclosure. The Lorentz force and Joule heating have adverse effects on flow, thermal field, heat transfer, and entropy generation. Adding nanoparticles enhances both heat transfer and entropy generation, with a higher enhancement in entropy generation compared to heat transfer. The relative slip velocity of nanoparticles diminishes as the magnetic field becomes stronger.

Summary: This study investigates the heat-transferring properties of engine oil with MHD effects using Ellis nanofluid, which contains copper (Cu) and Titanium oxide (TiO2) nanoparticles. The movement of engine oil is influenced by the presence of Cu and TiO2. Various factors such as viscous dissipation, thermal radiation, heat flux model, joule heating, and heat generation affect the energy equation. Mathematical representations are used to describe permeability, entropy creation, and a flat moving surface with non-uniform elongating velocity. The numerical technique bvp4c is employed to solve complex differential equations and analyze the flow and heat-transferring facets of Cu-TiO2. The study concludes that temperature and heat transfer rate decrease due to certain limitations, but these fluids can be used with caution in applications requiring heat transfer control. The findings contribute to the understanding of engine and generator cooling systems, aircraft refrigeration systems, nuclear cooling systems, and other technologies.

Summary: Researchers have expressed a strong demand for more reliable and long-lasting power storage devices. They have explored three more effective methods for storing heat energy: latent heat storage, sensible heat storage, and chemical heat storage. In addition, the behavior of a two-dimensional Maxwell nanofluid on a stretchable surface has been investigated, and the influences of various factors, such as Maxwell fluid parameter and magnetic field parameter, have been examined. It has been found that the velocity of the nanofluid increases with the enhancement of the Maxwell fluid parameter, while it decreases with the decrease in the magnetic field parameter. Moreover, the increase in Brownian motion and thermophoresis parameters leads to an increase in fluid temperature.

Results show that a large value of lambda 1 can enhance velocity, entropy generation, and heat transfer rate, while reducing temperature; whereas a large value of delta increases velocity and temperature but decreases heat transport and entropy generation number.

Summary: In this study, the effects of electrokinetic phenomena on entropy are investigated. The microchannel is modeled with an asymmetrical and slanted configuration, taking into account fluid friction, mixed convection, Joule heating, presence and absence of homogeneity, and a magnetic field. The governing flow equations are linearized using the Debye-Huckel and lubrication assumptions, and the resulting nonlinear couple differential equations are solved using Mathematica. Homogeneous and heterogeneous reaction parameters have different effects on concentration distribution, and the Eyring-Powell fluid parameters show opposite relations with various variables. The overall increase in fluid temperature and entropy is influenced by the mass Grashof number, Joule heating parameter, and viscous dissipation parameter.

Summary: This study investigates the magnetized flow of Ag-MgO/water hybrid nanofluid over an extending sheet implanted in Darcy porous medium. Various factors such as thermal radiations, Joule and viscous dissipations are considered to understand the heat transfer. The non-similar conversions are used to convert the governing equations into a system of dimensionless partial differential equations (PDEs) and then transformed into ordinary ones using the local non-similar method. Numerical simulations are conducted using MATLAB's bvp4c function, and the results illustrate the effects of key parameters on velocity and thermal profiles. This work contributes to the understanding of thermal systems and solar energy harvesting.
