摘要
该文论述了两种彩色滤光片/刀口法纹影技术在复杂流场显示中的应用。用该方法获得了底部排气弹超音速风洞试验的彩色纹影图片,并按照纹影技术理论对结果进行了分析和计算。
Two kinds of colour filter/knife methods for introducingcolour into a schlieren system have been developed. By using the colourschlieren system flow visualization of a complicated flow field in thesupersonic wind -- Tunnel experiment has been investigated.Photogrophs of coloured schlieren for Base--Bleed--Projectile taken inthe experiment are shown and the results are discussed.
