| 摘 要： | 介绍白光纹影流场检测系统的组成,测量原理和计算分析,并以酒精灯火焰和电吹风作为测试段的扰动场得到实验结果。纹影法的原理是用刀口在焦点处去切割光源像,把光线受流场的扰动转变为记录平面上的光强分布,从而对流场进行显示和测量。

| Abstract: | The paper introduces the system constitution?measurement principle and calculation analysis of the white light schlieren experimental system,and the results are obtained by using alcohol bumer and electric orier as perturbation field of test segment.The schlieren's principle is that lamp-house image is incised by knife-edge at fouse.,and it makes the perturbation ray of light by flow field into light intensity distribution on flat surface,consequently the flow field is displayed and scaled. |

| Keywords: | white light schlieren system flow field schlieren figure |
