Summary: This study numerically investigates the motion of a non-homogeneous hybrid mixture over a static wedge surface in a Darcy-Forchheimer porous medium. The simulation accounts for various factors including radiative heat flux, magnetic forces, and Joule heating. The results show the effects of these factors on temperature, velocity, and nanoparticles volume fraction, and reveal that the hybrid nanoliquids have a higher heat flux rate compared to monotype nanoliquids and liquids cases.

Summary: The study extends the incompressible Falkner-Skan-Cooke (FSC) boundary layer to the compressible regime and establishes a compatible compressible FSC flow with the two-dimensional compressible Blasius boundary layer. The crossflow is parameterized by introducing pressure-gradient parameter and local swept angle, leading to moderate directional deviation of skin friction and distortion of vorticity inside boundary layer. The crossflow strength varies monotonously with the pressure-gradient parameter and non-monotonously with the local swept angle.

Summary: This paper investigates the impact of unsteady hybrid nanofluid flow on a moving Falkner-Skan wedge with a convective boundary condition. Through the conversion and numerical solution of partial differential equations, it is found that dual-type nanoparticles and wedge angle parameters improve thermal efficiency, while the unsteadiness parameter and the Biot number of the working fluid have little effect on efficiency.

Summary: This article focuses on the application of graphene oxide-water nanofluid in Falkner-Skan hydromagnetic wedge flow. The effects of velocity and thermal slip phenomena, as well as viscous dissipation and ohmic heating, on heat transport are investigated near the stagnation point. The results show that increasing the Brinkman number leads to temperature rise, while thermal jump reduces the temperature field. This research is significant for medical treatment, high-temperature devices, heat exchangers, and mechanical structures.

Summary: In this article, the boundary layer flow of a two-dimensional Carreau fluid induced by a heated inclined flat plate is investigated. The flow is characterized by the variable viscosity of the Carreau fluid, and the dependence of thermophysical properties on temperature and concentration is analyzed. The governing equations are solved using the Falkner-Skan solution and a shooting method. The obtained solutions reveal the effects of shear-thinning and thickening on the fluid behavior, as well as the variations in base flow, temperature, and concentration profiles.
