Summary: This study investigates the mixed convection flow of a hybrid nanofluid in an inclined channel with top wall-slip, under constant heat flux conditions. Explicit analytical solutions in non-dimensional forms are provided for flow velocity, temperature, and pressure. It is found that both the hybrid nanofluid and wall-slip delay the occurrence of flow reversal in the channel.

Summary: This study investigates the flow and heat transfer characteristics of a dusty hybrid nanofluid flow over an unsteady shrinking sheet in the presence of a magnetic field. The results show that the skin friction coefficient and the local Nusselt number increase with higher magnetic field parameter, suction parameter, and mixture density ratio. However, they decrease with increased volume fractions of copper and alumina nanoparticles and Richardson's number. The occurrence of dual solutions also increases with higher volume fraction of alumina nanoparticles, Richardson's number, magnetic field parameter, suction parameter, and shrinking parameter. Moreover, the velocity of the hybrid nanofluid is accelerated with an increase of the mentioned parameters, while the temperature of the fluid becomes higher for larger values of volume fractions of nanoparticles.

Summary: This paper investigates the characteristics of dual solutions for an unsteady stagnation-point flow of a hybrid nanofluid over a rotating disk, considering the effect of Hall current. The governing equations are made dimensionless and solved numerically. The obtained solutions are compared with existing ones, showing good agreement. The solutions exist in the upper branch for all values of the hybrid nanofluid and certain parameters, while breakdown occurs in the lower branch solution at moderate values of one parameter. The radial velocity increases, while the azimuthal velocity decreases and the temperature increases due to the hybrid nanofluid. The swirl parameter enhances velocity in both directions but decreases temperature. Moreover, the azimuthal velocity and temperature decrease in the upper branch solution as the magnetic parameter increases, while the lower branch solution exhibits different behaviors.

Summary: This research investigates the heat transfer performance in stratified flow of hybrid nanoliquid over permeable stretched cylinder. The study focuses on heat transfer in a hybrid base fluid composed of ethylene glycol and water, with the addition of copper and alumina nanoparticles. The effects of porosity, Darcy-Forchheimer, Joule heating, radiation, viscous dissipation, and stratification on the thermal boundary are considered. The governing partial differential equations are transformed into ordinary differential equations and solved using the ND solve code in the MATHEMATICA package. The results show that velocity field and fluid temperature decrease with increasing porosity and Hartmann variables, while they decrease with decreasing Prandtl number and stratification parameter.

Summary: This study numerically investigates the flow of hybrid nanofluid with MHD and radiation effects over a permeable stretching/shrinking surface. By solving ODEs derived from the mathematical model, the study presents the stability analysis and graphical representation of flow and heat transfer characteristics. The findings indicate that only the first solution from the dual solutions is stable, and certain parameters can influence the boundary layer separation and heat transfer rate significantly. The originality of the study lies in providing new numerical results and potential future references for researchers in related fields.

Summary: This paper investigates the effects of hybrid nanoparticles and magnetic field on mixed convection boundary layer flow and heat transfer caused by an inclined shrinking-stretching surface in a hybrid nanofluid. Numerical solutions are obtained using MATLAB, showing that increasing the magnetic parameter significantly enhances heat transfer while increasing skin friction coefficient. Additionally, increasing the nanoparticle volume fraction is found to increase skin friction coefficient but decrease heat transfer rate. Multiple solutions are discovered, but only the first solution is stable according to temporal stability analysis.

Summary: The study investigates the concept of MHD mixed convection with Ag-TiO2 / H2O hybrid nanofluid flow over a slender cylinder and its applications in science and engineering. By applying a uniform magnetic field to analyze the impact on transport characteristics of the flow, the behavior of thermal efficiency is studied considering different nanoparticles shape factor. The simulation demonstrates that inclusion of hybrid nanoparticles in the base fluid results in higher heat transfer and the velocity of the hybrid nanofluid is enhanced with increasing values of mixed convection parameter and velocity ratio parameter.
