The elucidation of marangoni flow and micro liquid films structure in solid/gas/liquid interphase with the gas dissolution

在固/液/气三相界面即三相边界线上，伴随着气体的溶解、吸附等现象，表现为由浓度差和温度差引起的马兰哥尼流。外力，如液体频率，微重力和固相相对于液相的相对运动是在这个区域中操作，弯月面的边缘成为一个薄膜，并观察到，强烈的流动是由于浓度差的发展。这种现象在半导体制造和吸收式制冷机的清洗和干燥过程中得到了应用。如果在存在于这些设备的元件装置中的该区域中促进气体溶解现象，则将改善这些装置的局部部分中的传热和传质。设备和工艺的节能降耗工作也在进一步推进。这样的课题要求通过基础研究来精确地分析设备运行时的Marangoni流的流动行为。本研究旨在获得在这种情况的背景下控制边界中的传质现象的外部因素的基本知识。对Marangoni流所支配的各种传质现象进行了实验分析，得到了以下结果：界面振荡运动所产生的表面波的振动和振幅成分随固体表面的润湿性而变化。同时，我们也发现了马兰哥尼流对边界的动力作用。因此，我们澄清了一个方向的动力学效应承诺是相同的，无论固体表面的润湿性。此外，我们澄清了边界方向的速度的绝对值不同的固体表面的润湿性。

In solid/liquid/gas interfaces so-called the three-phase boundary line, with gas dissolution, adsorption phenomena, marangoni flow which is resulted from concentration difference and temperature difference is expressed. External force such as liquid frequency, micro gravity and relative movement of solid phase to liquid phase is operating in this region, a meniscus of edge becomes a thin film and, it is observed that intense flow is developed due to a concentration difference. This phenomena are applied cleaning and drying process in semiconductor manufacturing and absorption chiller. If gas dissolution phenomena are promoted in this region which exists in the element apparatus of these equipments, heat and mass transfer in a local part of these devices will be improved. And energy and resource saving of devices and the process come to advance further. Such a subject is asking for analyzing precisely a flow behavior of Marangoni flow at the time of the operation of apparatus through a fundamental research.This research aimed at acquiring the base-knowledge about external factors which is governing the mass transfer phenomena in the boundary against the background of such a situation. Various kinds of mass transfer phenomena which Marangoni flow governs were analyzed experimentally, and obtained the following results.We suggested that the vibrations and the amplitudes ingredient of the surface waves generated by the interface peristalsis movement change with wettability of solid surface. And, we detected the dynamic effect which works to the boundary by marangoni flow. Consequently, we clarified that a direction which a dynamic effect commits is the same regardless of the wettability of solid surface. Moreover, we clarified that absolute values of velocity of the boundary directions differ with wettability of the solid surface.
