Abstract
In this article, we study a supercritical mixture model enclosed in a rectangular cavity. The mixture is composed of two elements: the first is supercritical CO2 and the other is naphthalene. This article aims to study the cavity confinement effect on the mixture and the mass transfer adsorption with a heating plate and an adsorbent at the lower limit. The mathematical model used is based on the solution of the Navier-Stokes equations, associated with energy and mass diffusion equations, including the additional Peng-Robinson equation of state. These equations are solved under the assumption of a low Mach number. Under high heating of the lower plate, the results show an influence of the cavity confinement on the adsorption of the mixture and the mass transfer. Thus, an important cavity confinement for heights up to 0.25 mm leads to an increase in mass transfer. The results also showed that the convection flow is less intense and leads to an adsorption profile less homogeneous.
