实现定量测量是纹影技术发展的最新要求。制作一种彩色滤光片,代替传统“Z”字形纹影系统刀口,提出了一种能够定量测量轴对称流场密度场的纹影测量方法,提供了一种基于传统纹影装置的定性显示向定量测量探索的新途径。介绍了所提出的纹影定量测量方法的基本原理、标定方法和典型装置,以轴对称自由射流为研究对象,构建了典型的实验系统,并基于理论分析与数值模拟结果,对所获得的实验结果进行了对比。结果表明:所提出的彩色纹影定量测量方法适合于轴对称流场的密度场定量测量。

The quantitative schlieren measure ment is new development of schlieren technology. A color filter was made for the substitute of the typical "Z" schlieren knife. The quantitative color schlieren method was advanced for measurement of the density of the axial symmetry field. A new approach was researched for the development of the quantitative schlieren technology based on the typical schlieren setting. The measurement theory and calibration method were introduced, and the typical setting was given as an applied example. Take the axial symmetry free jet as an object, the theory analysis and computer simulation results were contrasted with the experimental data. The results show the given method is suitable for the density quantitative measurement of axial symmetry field.
