Homogeneous and binary nucleation: new experimental results and comparison with theory

Abstract

Experiments and the theory of homogeneous nucleation of nine vapours are compared on a unified basis. It seems that some of the gasdynamic experiments apparently yield nucleation rates that are much higher than those predicted by classical theory. However, a number of these results may have been caused by binary nucleation effects. Such effects are further discussed with experimental results for three binary systems. Problems and uncertainties associated with nucleation research are emphasized.
