Summary: This study investigates the magnetohydrodynamic flow of a water-based hybrid nanofluid containing ferrous and graphene oxide nanoparticles past a flat plate, taking into account the stagnation points, magnetic field and thermal radiation. The non-Newtonian behavior of the flow is also considered, and the proposed model is analytically solved using HAM. The results show that the velocity field is significantly reduced with increasing volume fractions of the nanoparticles, while the thermal field is increased. The viscosity of the flow is increased with a larger power-law index, resulting in an increased velocity field but an opposite effect on the thermal field.

Summary: This study investigates the impact of entropy generation on the irreversibility characteristics of various heat transport processes in a microchannel with ciliated walls. The mathematical model consists of nonlinear partial differential equations and is analyzed under the lubrication approximation theory. The study provides analytical solutions for the velocity, pressure, temperature, and concentration distributions, as well as expressions for entropy production rate and Bejan number. The results highlight the importance of including Hall current and the eccentricity parameter in controlling the irreversibility of thermodynamical systems in cilia-based micro-devices.

Summary: This study investigates the numerical analysis of MHD-free convective heat transfer and its interaction with radiation over a heated flame inside a porous semicircular cavity loaded with SWCNTs-water nanofluid for the first time. The results indicate that decreasing the heated region length is beneficial for enhancing natural convection, and increasing parameters such as Ra, phi, Rd, and Da result in a proportional increase in Nu(out) while Ha shows an inverse relationship. Furthermore, an increase in radiation and Hartmann number leads to a 4% increase and 56.55% decrease, respectively, in the average Nu on the heated length. Additionally, a rise in radiation number causes a 73% increase in the average Nu of the heated flame, and increasing the Hartmann number results in an 82.4% decrement of the maximum velocity profile in the vertical direction.

Summary: The study investigates heat and mass diffusion in 2D Cross nanofluid flow over a parabolic surface using the Cattaneo-Christov model, considering temperature-dependent viscosity, enthalpy change, and activation energy. The determining equations are generated in the form of PDEs and transformed into ODEs using similarity transformations, and numerical outcomes are analyzed using the BVp4c method in Matlab software. The velocity of fluid shows reverse results with increasing Weissenberg number and viscosity parameter, while larger values of thermal and concentration relaxation parameters indicate a decrease in the respective fields. Numerical results for skin friction coefficient, Sherwood number, and Nusselt number for various parameters are presented in tables.

Summary: The heat transfer and flow characteristics of Tiwari-Das model nanofluid inside a differentially heated square enclosure with single walled carbon nanotubes and water, considering thermal radiation, were investigated in this study. Numerical simulations were conducted to analyze the effects of various parameters on the heat transfer performance, showing that the addition of single walled carbon nanotubes can enhance the heat transfer rate of the nanofluid by up to 6%. Additionally, it was observed that the radiation parameter can increase the Nusselt number values inside the cavity. The numerical code used in this study was validated and showed good agreement with available data.

Summary: The research theoretically analyzed the heat transfer enhancement of hybrid nanofluids flowing through a porous medium in the presence of a magnetic field. The results showed that the flow speed increases with the Maxwell fluid parameter, while the increasing strength of the magnetic field and porosity resistance slows down the flow but causes a rise in temperature. Additionally, the additive volume fraction of silver with Graphene oxide helps decelerate the flow and enhance heat transportation.

Summary: This study examines the flow of nanofluid containing multi and single-walled carbon nanotubes submerged in Ethylene glycol in a Darcy-Forchheimer permeable media over a stretching cylinder with multiple slips. The mathematical model takes into account non-uniform source/sink impacts, modified Fourier law, and autocatalytic chemical reaction. Entropy optimization analysis is performed and the nonlinear system is converted to ordinary differential equations for solution using the Shooting technique and bvp4c MATLAB software. The study shows that a strong magnetic field enhances temperature profile and decreases velocity profile, while fluid velocity decreases with increasing slip parameter. Additionally, entropy number increases with higher thermal relaxation parameter and Reynolds number.
