Diffuse vaporization (sublimation) of a large aerosol particle under precipitous changes in the ambient temperature
Annotation
The steady-state diffuse vaporization (sublimation) of a stationary coarse nonspherical particle has been simulated mathematically in the situation when the ambient temperature changes considerably. The formulas found make it possible to estimate the rate of change of the temperature and the particle mass with regard to the particle surface shape, thermal diffusion, and temperature variations in the transfer coefficients. The analysis performed indicated that the rate of particle vaporization (sublimation) can depend strongly on the shape of the particle surface. Thermal diffusion can also pronouncedly affect the particle vaporization rate.
