NUCLEATION AND GROWTH IN THE DIFFUSION CLOUD CHAMBER II STEADY STATE NUCLEATION

A model describing nucleation and growth in a thermal diffusion cloud chamber presented earlier in this Journal to explain oscillatory nucleation is extended to the case of steady state nucleation. The model is applied to nucleation rate data for ethanol vapor obtained using a thermal diffusion cloud chamber. A correction is made for the deleterious effects of vapor depletion and latent heat generation which accompany droplet growth thus extending the accessible range of nucleation rate measurements by several orders of magnitude.
