摘要
介绍适用于激波风洞的表面油流流动显示方法及其典型显示结果。实验表明应用油滴、油膜及其组合等方法在 6～ 8ms的实验时间内 ,能够清晰地显示三维突出物干扰引起的层流分离、转捩分离和湍流分离流及其尾迹流谱。
This paper describes a surface oil flow visualization technique that is suitable for use in shock tunnels with the running time of 6～8 ms. By means of oil drop method or oil film method and their combination, the high spatial resolution oil flow patterns of flow separation induced by 3D-protuberances in turbulent or laminar flows could be obtained. Typical oil flow patterns are given.
