摘　　要：介绍了一种用于小如数流动显示研究的水平式肥皂膜水洞。该装置试验段流速稳定，流速范围为0．2～1．5m／s。采用了几种模型在该水洞中进行试验，试验结果表明，水平式肥皂膜水洞在研究小胁数流动显示方面具有独特优势，能够反映出物体在小胁数下的微细流动特征。A horizontal soap film used to study flow visualization at small Reynolds number was presented. In the test section of the soap film the flow speed ranges from 0.2 to 1.5 m/s. A series of tests with different modelswere conducted. The experimental results show its particular advantages in flow visualization at small Re number, then the details of flow field at small Re are visualized.
