Poly-Disperse Droplet Evaporation Model — Comparison With Experimental Results

Experimental data for the evaporation of micron-size, poly-disperse water droplets into air has been generated in order to validate a theoretical poly-disperse droplet evaporation model. The model considers air and droplets flowing along a tube and predicts changes in droplet sizes and temperatures as well as air temperature and humidity as functions of distance along the tube. There are small discrepancies between experimental and model results which can be explained in terms of the lack of mixing between the droplets and air stream and also possible settling of the larger droplets in the experimental apparatus.

Long-Lived Plasma Process, Created by Impulse Discharge in Micro-Disperse Droplet Environment

The processes of organic compound (phenol and cation-active surfactants) destruction in water solutions, which stay under the influence of plasma treatment have been investigated in different dynamic plasma-liquid systems (PLS) with discharges in droplet micro-disperse environments (DMDE). The long-lived plasma process with separate spectral properties has been observed for pulsed discharge in DMDE. The approximate computer model is being proposed for a description of this effect. According to the introduced model this long-lived process is the aggregation of correlated discharges between charged droplets.
