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

泡沫在各种水加工中的应用在节水和节能中的直接影响广泛引起了人们的注意。通过用小比热的气体（例如空气）更换大部分大型热量的水，可以预期节水和温度升高和热隔热所需的能量，尤其是在高温加工中。在这项研究中，它注意液体流动非常有效地对洗涤动作和染色体产生的染色和染色体在FOAM上产生了良好的融合，并在FOAM中产生了染色器，并在FOAM中产生了FOAM，并在FOAM中产生了FOAM，并在FOAM中产生了FOAM，并在FOAM中产生了FOAM的构造。气泡。因此，构建了该液体的速度测量系统。根据先前的研究，泡沫膜是通过对烧瓶中表面活性剂溶液的气体（空气）注入产生的。此处生成的气泡或膜被导致电池进行观察，并在S ...中设置了更多显微镜标签，玻璃管等。高速摄像机是在该显微镜设备中设立的，并且在通常的情况下对高速液体流的观察非常困难。观察后的气泡通过玻璃管等诱导到陷阱，并被损坏。此外，进行了液体流量观察和流速测量的条件设置。 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 necessary confirmed it was not constant but so-called turbulent flow was generated.另外，当速度元件分为两个方向（与泡沫膜和平行的角度直角）时，平行元件较大。很明显，沿高原边界长度方向的液体流动更加活跃。较少的
