Nucleation in superheated gas-saturated solutions. I. Boiling-up kinetics

Nucleation in a superheated gas-saturated solution is regarded as a diffusi onal process in the space of three variables of a nucleus: Its volume upsil on and the partial pressures of the components p(1)",p(2)". The paper deter mines the surface relief of the thermodynamic potential in the vicinity of the saddle point and describes the growth of vapor bubbles in a solution wi th allowance for its viscosity, rate of evaporation of molecules of a solve nt, and a dissolved substance, rate of diffusional supply of a substance to the bubble surface. The tensor of the generalized diffusion of nuclei, the decrement of increase of an unstable variable, the stationary nucleation r ate have been calculated. (C) 1999 American Institute of Physics.
