在许多工业和环境应用中，通过液体表面处气泡的破裂将材料从液相转移到气相是令人关注的，例如，废水处理厂和健身俱乐部游泳池产生的微生物。以往的研究大多集中在单气泡破裂，这是很少发现在实际情况。已经开发出一种实验系统，该系统足够大以适应多气泡破裂，并且克服了在起泡液体的表面上方的液滴的取样和分析的困难。该系统使用动态气溶胶光谱仪提供关于所产生的液滴的浓度和尺寸分布以及液滴蒸发后液滴中所含物质的实时信息。专门设计的撞击器用于对液滴进行尺寸分类，以便可以评估各种尺寸范围的液滴的含量。测量液滴分布的实例
The transfer of materials from the liquid phase to the gaseous phase by the bursting of gas bubbles at the liquid surface is of concern in many industrial and environmental applications, e.g., microorganism generation from wastewater treatment plants and health club whirlpools. Most previous studies have focused on single-bubble bursting, which is rarely found in actual situations. An experimental system has been developed that is large enough to accommodate multiple-bubble bursting and overcomes the difficulties of sampling and analysis of liquid droplets above the surface of a bubbling liquid. The system uses dynamic aerosol spectrometers to provide real-time information on the concentrations and size distributions of the liquid droplets generated and of the materials contained in the liquid droplets after their evaporation. Specially designed impactors are used to size classify the droplets so that the content of the droplets of various size ranges can be evaluated. Examples of measured droplet distrib...
