| 摘 要： | 把表面活性剂加入水流中形成的乳化空气泡，作为ＰＩＶ流场显示的踪粒子，并对套筒间的旋转环流场进行了ＰＩＶ测量，流场定量实测结果令人满意。这亦表明乳化空气泡是一种品质较高且经济适用的ＰＩＶ水流示踪粒子。

| Abstract: | By seeding a sort of surface agents,the emulsifying air-bubbles are formed,which are used as the tracer particles in PIV flow visualization.The rotational circulation flow fields in a sleeve barrel are successfully researched by using PIV system.The measured results show that the emulsifying air-bubbles are of good quanlity and cheap tracers. |
