The application of the foams to various water processing is widely noticed for its immediate effects in water saving and energy conservation. By the replacement of the majority of water of large specific heat with a gas (such as air) of small specific heat, the water saving and the great reduction of energy necessary for the temperature rise and heat insulation can be expected especially in the high temperature processing.In this research, it paid attention to the point that liquid flow extremely effective to the washing action and the dyeing is generated in the Plateau border, in the foam or composed by the contact part of foam film and the substrate, positively moving the bubble. Therefore, the velocity measurement system of this liquid flow was constructed. According to the previous research, the foam film was generated by the gas (air) injection to the surface-active agent solution in the flask. The bubble or film generated here was led to the cell for the observation, set on the s … More tage of the microscope, by the glass tube etc. The high-speed video camera was set up in this microscope device, and the observation of a high-speed liquid flow, extremely difficult under a usual condition, was enabled. The bubble after the observation was induced to the trap by the glass tube etc., and was broken.Moreover, the condition setting for the liquid flow observation and the flow velocity measurement was done. The observation target was the transparent colorlessness foam film basically formed with the surface-active agent solution, and the movement of the minute solid polystyrene particle polystyrene etc. as detector was assumed to analyze considering the liquid flow.The liquid flow that had a faster speed than the passing speed of the foam film was admitted in the Plateau border as a result of the observation and the direction was necessarily confirmed it was not constant but so-called turbulent flow was generated. In addition, when the speed element was divided into two directions (right angle with the foam film, and the parallel), the parallel element was the larger. It became clear that the liquid flow along the direction of length of the Plateau border was more active. Less

泡沫塑料在各种水处理中的应用因其节水节能效果立竿见影而受到广泛关注。通过用小比热的气体(如空气)代替大部分大比热的水，尤其是在高温加工过程中，可以预期节水和大大降低温升和隔热所需的能量。在本研究中，注意到液体流动对洗涤作用非常有效，染色产生在高原边界，在泡沫中或由泡沫膜与基材的接触部分组成，正向移动气泡。为此，构建了该液体流动的测速系统。根据前人的研究，泡沫膜是通过向烧瓶中的表面活性剂溶液中注入气体(空气)而产生的。这里产生的气泡或胶片被引导到细胞进行观察，设置在S…上在该显微镜装置中设置了高速摄像机，从而能够观察在通常情况下极其困难的高速液体流动。用玻璃管等将观察后的气泡诱导到捕集器上，使气泡破裂，并对液体流动观察和流速测量的条件进行了设置。以表面活性剂溶液基本形成的透明无色泡沫膜为观察对象，假设微小固体聚苯乙烯颗粒聚苯乙烯等作为检测器，考虑液体流动，在高原边界引入速度快于泡沫膜通过速度的液体流动，并必然确认其方向不是恒定的，而是产生所谓的湍流。此外，当速度元件被分成两个方向(与泡沫膜成直角和平行)时，平行元件较大。结果表明，沿高原边界长度方向的液体流动较为活跃。较少
