Abstract
The mixing of a wet vapor with a gas is studied using analytical and numerical models. The one-dimensional problem of diffusion mixing accompanied by phase transitions is solved in a self-similar formulation. The versions of mixing of the vapor with a cold and warm gas and with a superheated vapor are analyzed. The atmospheric diffusion of immediate emissions containing water vapor and condensate is modeled numerically in a three-dimensional formulation. A study is made of the evolution of hydrodynamic, concentration, and temperature fields as a function of the initial emission parameters (temperature and humidity) and ambient air parameters.
