Summary: The study investigates entropy generation in mixed convection flow of incompressible viscous fluid along a wavy cone, revealing the impact of surface curvature on entropy generation and the potential to manipulate entropy production through surface alteration. By studying the influence of physical parameters, such as cone half angle and Richardson number, on entropy production, it is found that minimizing energy loss can be achieved. The Bejan number categorizes the dominant role of thermal and viscous irreversibility in entropy production.

Summary: A study was conducted on the stagnation-point flow of Powell-Eyring nanofluid, taking into consideration the buoyancy force effect due to mixed convection, as well as the impact of Brownian motion and thermophoresis. Stagnation has a bigger influence under passive control of nanoparticles. Assisting flows exhibit better heat and mass transfer rates.

Summary: This study numerically investigates the magnetohydrodynamics of a micropolar fluid consisting of a hybrid nanofluid with mixed convection effects using the bvp4c solver in MATLAB. The results show that the hybrid nanofluid has the highest critical value of opposing flow and the nanoparticle volume fraction enhances the dynamic viscosity performance and surface shear stress.

Summary: The present study focuses on the analysis of the Micropolar Carreaufluid model over a vertical Riga sheet using the Cattaneo-Christov heat flux theory. The partial differential equations are transformed into ordinary differential equations through specific transformations, and a numerical scheme is employed to solve the model. The results reveal that the skin friction increases while the couple stress decreases with the boosting values of the buoyancy ratio term. Both the velocity and temperature functions exhibit consistent behavior with the variations in the dimensionless parameter.

Summary: This paper numerically analyzes the stagnation point flow of Cu-Al2O3/water hybrid nanofluid with mixed convection past a flat plate and circular cylinder. The study finds that an increase in the curvature parameter tends to extend the critical value and improve heat transfer performance. The application of hybrid Cu-Al2O3/water nanofluid can decelerate the separation of laminar boundary layer flow and generate higher heat transfer rates compared to Cu-water nanofluid and pure water.

Summary: The flow of a water-based alumina-copper hybrid nanofluid in an inclined cylinder with the impact of buoyancy force and a magnetic field is investigated in this study. The governing partial differential equations are transformed into a set of similarity ordinary differential equations, and then solved numerically using MATLAB software. The results compare well with previously published results.

Summary: This study numerically investigates the two-dimensional mixed convection of a hybrid nanofluid with radiation, Dufour, and Soret effects. It is found that using 2% copper nanoparticles and minimizing the Dufour effect can prevent boundary layer separation and enhance heat transfer rate. Stronger mixed convection leads to higher skin friction, mass transfer, and heat transfer rates.

Summary: This study analyzes the magnetohydrodynamic pulsatile flow of third grade hybrid nanofluid in a porous channel under the impacts of viscous dissipation, thermal radiation, and Ohmic heating. The findings of this research are significant in various fields including food processing, biomedical engineering, and pharmaceuticals. The study investigates the pulsating flow of a third grade hybrid nanofluid with thermal radiation and Joule heating effects, which has not been reported before. The study demonstrates that velocity decreases with a rise in Hartmann number and non-Newtonian parameter, while the temperature of the nanofluid is enhanced with increasing viscous dissipation.

Summary: This study conducted a numerical analysis on the unsteady magnetohydrodynamic mixed convection at a three-dimensional stagnation point flow, revealing that the enhancement of suction/injection and magnetic parameters exaggerates heat transfer rate and skin friction coefficient, while the increase in volume fraction of nanoparticles and decrease in unsteadiness parameter lead to a decrease in performance.
