Experimental study of evaporation of distilled water and 10% NaCl and СaCl₂aqueous salt solutions droplets under their free falling on a heated surface

Abstract

The paper presents the experimental results of evaporation of distilled water and 10% aqueous salt solutions of NaCl and СaCl 2 droplets under their free falling on a heated surface. It is proved that it is more expedient to conduct the experimental research in this field according to classical multifactorial experiment. Laser treatment of surfaces is found to increase the evaporation rate and to biases the point of boiling crisis in the region of lower surface temperatures. In this case, in the conditions of boiling crisis the frequency of contact of a droplet with a heated surface will decrease.
