实验研究了在常压热气流中，液滴与环境气流的相对速度对直径为180 μm的正庚烷自由液滴蒸发速率常数的影响。液滴直径和速度的测量是在一系列的时间通过电控光学系统进行。根据实验结果，得到了蒸发速率常数与相对速度关系的经验公式。
An experimental study has been performed to obtain the effect of relative velocity between droplet and ambient flow on the evaporation rate constant of a nheptane free droplet of 180 μm in diameter flying in a hot and normal pressure air flow. Measurements of droplet diameter and velocity were conducted in a series of time elapsed by an electrically controlled optical system. From the experimental results, an empirical equation associated with the relation between evaporation rate constant and relative velocity was obtained.
