| Summary: | Title screen Micro-explosive fragmentation of liquid droplets can significantly change the distribution of the dispersed phase in gas–vapor-droplet flows. After monitoring the dispersed phase, it was hypothesized that mutual and cascade effects might occur in such flows depending on the heating rate. Until now, these effects have been studied by heating several droplets in a gas-air environment. Sprays consist of very fine droplets. Mutual and cascade effects may manifest themselves in different ways. Research findings on mutual and cascade effects during a micro-explosion of a cloud of droplets are reported in this study. It deals with the mechanisms of these effects, as well as the necessary and sufficient conditions for them. The number of parent droplets was varied from 20 to 60. Two-liquid droplets based on Diesel fuel, n-dodecane, rapeseed oil and water were used. Functional relationships between heating and evaporation characteristics of droplets to the mutual and cascade effects of their micro-explosive fragmentation were identified. The physical models describing these effects were developed based on experimental data. Using a mathematical model, conditions for the implementation of collective effects of micro-explosive fragmentation of heterogeneous droplets in sprays were predicted Текстовый файл AM_Agreement |
