摘要
The evaporation of droplets in non-dilute and dilute monodisperse droplet clouds has been studied both experimentally and theoretically. This study presents quantitative experimental data for monodisperse cloud evaporation. Experiments are performed in an insulated evaporation tube under weakly convective flow conditions at atmospheric pressure. Nearly monosize tetralin clouds having a mean diameter of 30 μm are used for the experiment. For a non-dilute cloud investigated, the evaporation rate is significantly lower than that of a single droplet and evaporation may stop due to saturation. An improved version of droplet-in-bubble model, adopted to describe the evaporation within non-dilute monodisperse clouds, exhibits excellent simulation of the experiments. © 1992.
