Abstract

A new method is proposed for determining the rate of evaporation of a group (cluster) of droplets during their gravitational sedimentation in a high-temperature gas medium. Results of experimental investigation of the evaporation of clusters of distilled-water droplets of 0.77-mm radii in air at temperatures within 650–800 K are presented. It is established that the evaporation rate significantly decreases with reduced distance between droplets in the cluster.

在高温气体介质中移动的液滴簇的蒸发

摘要

提出了一种确定液滴在高温气体介质中的重力沉降过程中的蒸发速率的新方法。给出了在650–800 K的温度下空气中0.77 mm半径的蒸馏水滴团簇蒸发的实验研究结果。已经确定，随着簇中液滴之间的距离减小，蒸发速率显着降低。
