Mixed Convection Ferro Fe₃O₄/Cu-Hybrid-Nanofluid Flow in Vertical Flat Microchannel

Mixed convection of Ferro hybrid nanofluid (Fe 3 O 4 + Cu/H 2 O) in a vertical-oriented microchannel with slip boundary conditions has been taken into account in this article. The sides of channels are assumed to be heating linearly; under these assumptions, a system of partial differential equations of momentum and energy has been considered. Using the non-dimensional variable technique, the partial differential equation was converted into an ordinary differential equation and solved analytically. Varying the relevant parameters significantly affects the velocity and temperature profile, as well as the Nusselt number. The results revealed that hybrid fluid, Knudsen, and Rayleigh numbers all affect the velocity and temperature behavior. Referring to the obtained results, shear stress is reduced by 10% as the nanoparticles increase from 5 to 10%. Also, shear stress reduced by increasing hybrid nano-particle.
