| 要約: | Title screen The effect of typical admixtures (clay, sand, soil, and silt) on the integral evaporation characteristics of aqueous suspension drops in high-temperature gases (at nearly 1100 K) has been experimentally studied using optical methods and a high-speed video record system (up to 105 fps). The heating and evaporation of suspension drops was established to appreciably intensify with a change in the relative mass fraction of admixtures within ? = 0–0.1 for sand and ? = 0–0.01 for clay, soil, and silt. An essential effect of the preliminary heating of suspensions on the intensity of their evaporation in a flow of high-temperature gases has also been revealed. Some recommendations have been formulated for selecting evaporation parameters for the studied suspensions in contemporary and advanced high-temperature chemical and thermal engineering technologies for the purification of water from admixtures and in the sphere of fire safety.
