Abstracts:

The experimental data on the nucleation rate within the surface of the water droplet which are blown by the dry air flow are presented at the present publication. A simplified model of the droplet mass going down intensification as the result of a spontaneous generation of the vapor embryos at the droplet surface is suggested. The single water droplets near 2 mm in diameter were blown by the dry air flow with the linear velocity from 2 to 5 meters per second. The infrared imager (Thermo Tracer TH7102MV) was used for the temperature distribution measurements on the droplet surface. The time variation of the droplet sizes and the dynamics of boiling centre number were measured as well. The used gauge scheme can be applied for the wide spectrum of quantitative measurements of the vapor embryos generation rates (frequencies) on the droplet surfaces which are blown by dry gas.
