本文详细描述了一种使用流动肥皂膜进行二维流体动力学实验的装置。我们之前曾报道过使用该设备取得的科学发现，但从未仔细描述过该技术或其全部潜力。简要介绍了皂膜作为流体的性质，然后列出了创建坚固的流动膜所需的所有细节。该系统的典型参数为：流速为 0.5 至 4 m/s，薄膜厚度为 1 至 10 μm，典型薄膜尺寸为 3 m 高和 10 cm 宽，尽管也制备了 20 m 高和 4 m 宽的薄膜。还描述了一种真空装置，其中薄膜上的空气阻力可以减少 5-10 倍。最后，概述并引用了大量测量流量和厚度的技术。
This article gives a detailed description of an apparatus in which flowing soap films are used to perform two dimensional fluid dynamics experiments. We have previously reported scientific findings made with the apparatus, but never carefully described the technique, or its full potential. A brief introduction is given on the nature of soap films as fluids and then all the details necessary for creating robust flowing films are listed. Typical parameters for the system are: flow speeds from 0.5 to 4 m/s, film thickness between 1 and 10 μm, and typical film sizes are 3 m tall and 10 cm wide although films of 20 m tall and 4 m wide have also been made. A vacuum apparatus is also described in which the air drag on the film can be reduced by a factor of 5–10. Finally, a large number of techniques for measuring flow and thickness are outlined and referenced.
