摘要

本文介绍了一种考虑地表恒温风速计传感器读数的粒子图像测速数据时频分析的新方法。该方法基于计算粒子图像测速数据与在给定频率范围内过滤的恒温风速数据之间的相关系数。这种方法可以在一个频率范围内获得整个测量范围内流动的非定常特性数据，该频率范围的边界超出了粒子图像测速频率范围的边界。将该方法应用于马赫数M = 1.43时激波与边界层相互作用区域的非平稳过程研究。

SURFACE CONSTANT-TEMPERATURE ANEMOMETER SENSORS USED TO ANALYZE PARTICLE IMAGE VELOCIMETRY DATA

This paper describes a new method for performing the time-frequency analysis of particle image velocimetry data with account for surface constant-temperature anemometer sensor readings. This method is based on calculating correlation coefficients between particle image velocimetry data and constant-temperature anemometer data, previously filtered in a given frequency range. This approach makes it possible to obtain data on the unsteady characteristics of flows throughout the entire measurement range in a frequency range whose boundaries extend beyond the boundaries of the particle image velocimetry frequency range. The proposed method is applied to study nonstationary processes in a region where a shock wave interacts with a boundary layer at a Mach number M = 1.43.
