Abstract

Experimental research on the influence of the content of typical salt admixtures in water on integral characteristics of its evaporation while moving through a high-temperature gas medium was carried out using NaCl nanopowder. Experiments were conducted with single large (more than 1 mm) drops and an aggregate of (more than one hundred) small (under 0.3 mm) water droplets moving through a channel filled with high-temperature combustion products. Conditions were determined under which the content of salt admixtures in water has a strong effect (the decrease of mass changes several times) on the intensity of evaporation of the latter in the region of hightemperature gases.
