Abstract

A mathematical model of the motion of aerosol drops in a thermal diffusion chamber due to the action of thermodiffusiophoresis and the gravity force is proposed, taking into account phase transitions on the drop surface. The model includes the equation of motion of the drop and an equation describing the change in its radius during condensation. The dependence of the kinetic coefficients on the temperature and composition of the mixture is neglected, which imposes certain limitations on the permissible value of the temperature change in the region considered. A formula is obtained for the height of maximum ascent of the drop. The results of calculations using this formula are compared with experimental data [1] and with the results obtained using the free-molecular theory. The proposed model gives more satisfactory agreement with experimental results.
