摘要

我们介绍了一项关于纤维上液滴蒸发的实验研究。更具体地说,我们重点研究了液滴在静止空气和匀速气流中的寿命。我们提出了一个模型来描述纯扩散体系中的蒸发率和寿命,其中包括与蒸发相关的液体冷却以及大气和纤维的导热性。我们的模型有效地捕捉到了主要的物理行为,与我们对各种液体和纤维材料的测量结果呈现出半定量的一致性。最后,该模型被推广到对流气流中,这也使我们的实验数据更加合理。

Thermal effects on the lifetime of evaporating drops on fibers†

Thermal effects on the lifetime of evaporating drops on fibers†

We present an experimental study on the evaporation of drops on fibers. More specifically, we focus on the droplet lifetime both in quiescent air and in an air flow of constant velocity. We propose a model to describe the evaporation rate and lifetime in a purely diffusive regime, which includes the liquid cooling associated with evaporation and the thermal conductivity of the atmosphere and the fiber. Our model effectively captures the primary physical behaviors, demonstrating a semi-quantitative agreement with our measurements across various liquids and fiber materials. Finally, the model is generalized to a convective air flow, which also rationalizes our experimental data.
