摘要

本文研究了湍流射流速度剖面测量的准确性。通过将图像处理技术应用于纹影方法来获得测量结果。这里描述的纹影方法相对较新，在过去几年中首次获得专利并使用。通常，考虑到湍流的路径综合性质，应用于湍流的SIV方法会产生不可编辑/不相关的数据。文中还讨论了全局测量误差及其减小方法。

Schlieren image velocimetry methods for a round, hot, turbulent air-jet

The present article investigates the accuracy of measurements regarding the velocity profile of a turbulent jet. The measurements are obtained by applying image processing techniques to schlieren methods. The schlieren methods described here are relatively new, having been patented and used for the first time in the last few years. Generally, SIV methods applied to turbulent flows result in unrelatable/ unrelated data, given the path-integrated nature of the flow. The global measurement errors and ways to reduce them are also discussed.
