Abstract:

This article studies the dissipative structure, consisting of organized monolayer of water droplets, levitating above the locally heated and evaporating water layer — the phenomenon called “droplet cluster”. The droplets come to the cluster from gas environment, where they form and complete the process of primary condensing growth. Dimensional cluster localization discovers new opportunities in research of complex physical and chemical processes in mist spray droplets. For example, quickness of condensing growth of chosen, monitored during a time period droplet, can be measured by the means of optical microscopy.

The author investigates the previously undescribed possibility of measuring cluster droplets diameter using the ILIDS (Interferometric Laser Imaging Droplet Sizer) method. Interferometric imaging measurements are as accurate as direct imaging measurements of droplet size. At the same time, they have a number of benefits for realization of effective automatic video stream analysis algorithms.
