毛细尺度固着液滴的流体力学和蒸发

Hydrodynamics and evaporation of a sessile drop of capillary size

L. Yu. Barash

摘要:

介绍了毛细尺寸的无座蒸发液滴的流体动力学视频。相应的模拟表示的描述,同时考虑到时间相关的流体力学,蒸汽扩散和热传导在蒸发固着液滴。液滴中的流体对流由与表面张力的温度依赖性相关联的Marangoni力驱动。首次获得了蒸发过程中液滴内涡结构的演化规律。

英文摘要:

Fluid dynamics video of an evaporating sessile drop of capillary size is presented. The corresponding simulation represents the description taking into account jointly time dependent hydrodynamics, vapor diffusion and thermal conduction in an evaporating sessile drop. The fluid convection in the drop is driven by Marangoni forces associated with the temperature dependence of the surface tension. For the first time the evolution of the vortex structure in the drop during an evaporation process is obtained.
