Integral Characteristics of Motion of Droplets of Liquids in Gas Media

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The authors have given results of experimental investigations into the integral characteristics of motion of droplets of liquids in gas media as functions of the velocity of motion of a medium and its temperature and of the concentration of a vapor in it. Emphasis was placed on recording the size distributions of liquid droplets on different portions of motion of the gas medium. A study has been made of the velocity of motion of the gas and its temperature and of the concentration of the vapor in it on the distribution of the droplets in a vapor–gas flow. The authors have been determined conditions with which each of the indicated parameters exerts a decisive influence on droplet distributions in the gas medium, and also conditions with which the influence of these parameters is small. Ratios of the rate of decrease in the size of the droplets to the velocity of their motion have been computed using the results of the conducted experiments. The distributions of liquid droplets in a moving gas medium ahead of the combustion front have been predicted under the conditions corresponding to the localization of and fighting a forest fire.
