The Impacts of Shape Factor and Heat Transfer on Two-phase Flow of Nano and Hybrid nanofluid in a Saturated Porous Medium

Abstract The focus of this article is to obtain the effect of the shape factor of the hybrid nanoparticles on the convective heat and mass transference of two immiscible fluids in an inclined duct. Nanoparticle such as Carbon Nanotube & Sodium alginate is considered with Silicon oil as the base fluid. By considering the heat and mass phenomena, viscous dissipation, Darcy and Thermal diffusion the governing equations are formed. The physical flow model is then modelled into a set of differential equations, which are then reduced to the dimensionless form and the regular perturbation technique is employed to obtain the solution for velocity, temperature and concentration. The effects of various material parameters are analyzed using graphical and tabular forms. From the results, it is noticed that the lamina shape hybrid nanoparticle has a higher heat transfer rate compared to others and the significance of the soret number can be seen in velocity and concentration distributions.
