“…The key for the explanation of most phenomena associated with the activity of comets is a proper understanding of the processes taking place within a thin layer around the nucleus/coma interface [5,6]. Heat and mass transfer at sublimation of solid particles is important in the development of new technologies of chemical vapor deposition [7,8]. For intensifying and optimizing the operation modes for the low-temperature drying of pharmaceutical and food products the knowledge about the sublimation-deposition phenomena are also indispensable [9,10].…”

The sublimation and deposition behaviors of the Helium-Argon mixture is analyzed numerically in the temperature range where Helium is only in gaseous state while Argon can sublimate and deposit on its own solid phase. The Mc-Cormack model is implemented to model the Boltzmann collision term. Three kinds of potential are used for simulation of the intermolecular collisions: Hard Sphere, Lennard-Jones potential, and ab initio. The matrices of the kinetic coefficients have been obtained for different values of the rarefaction parameters and molar fraction of non-sublimating gas. The influence of the intermolecular potential on the kinetic coefficients as well as on the gas macroscopic profiles has been analyzed.

The paper presents the results of numerical simulation of nonstationary sublimation of spherical particles of Cr(acac)3, floating in the volume of a binary mixture (argonsuperheated vapor of precursor) in a reactor with hot walls. The influence of the vapor content, reactor wall temperature and radiative heat transfer on the kinetics of sublimation/desublimation are analyzed. The characteristic times of induction and total sublimation, as well as the intensity of mass entrainment from the surface of particles of different sizes are determined. The influence of radiation from the hot walls of the sublimator on these parameters is determined.
