The effect of evaporation on the oscillation angular frequency of an inviscid drop is analytically investigated. The evaporation is found to increase the oscillation frequency, and this is driven by two non-dimensional parameters, one accounting for the fluid properties and the other for the evaporation conditions. An investigation of the conditions for which the effect can be detected is reported for some evaporating species; low pressure environment enhances the variation of the oscillation frequency with respect to the non-evaporating case and the magnitude of this effect is quantified.

蒸发对无粘液滴振荡频率的影响


分析研究了蒸发对无粘性液滴振荡角频率的影响。发现蒸发会增加振荡频率，这是由两个无量纲参数驱动的，一个考虑流体特性，另一个考虑蒸发条件。据报道，对某些蒸发物种可检测到该效应的条件进行了调查；相对于非蒸发情况，低压环境增强了振荡频率的变化，并且这种效应的大小是量化的。
