Abstract
The evaporation of spray injected in material and mechanical engineering has significant effect on mixture formation, emissions and power output. In fact, for only micro-droplets in regular arrangement, fluid motion, supercritical and various shapes changed with time and so on, these common phenomena are quite complex and difficult to be understood and simulated. Especially, the studies of latest decade can show the development level of the relevant models, which will be reviewed in this paper. Some typical traditional quasi- and multi-dimensional models predicting various evaporation characteristics are reviewed for the newest developments to understand much more complex species, momentum and heat transport phenomena through the gas-liquid interface in industrial sprays with real operating conditions. Some experiments used to compare with these models developed are analyzed to reveal some aspect to be improved both for experiment and model. As can be seen from the comparison of the multidimensional results with the quasi-dimensional ones, the more comprehensive models are apparently in favor of understanding the micro-droplet evaporation better. Furthermore, the micro-droplet group shows more complex evaporation process than that of isolate micro-droplet.
