Abstract

One of the most important goals of experimental gas dynamics is to study formation and evolution of fluctuations generated by flow over some obstacles. Such fluctuations are mostly non-stationary. To analyze such experimental data time-frequency techniques are required such as Hilbert-Huang transform. In this paper some results of application of this technique for data analysis are presented. Specific features, advantages and disadvantages of transform are mentioned. Time series analyzed were obtained in experiments on fluctuations measurements behind a circular cylinder in two different wind tunnels at different speeds but close Reynolds number ranges. Amplitudes of fluctuations behind a cylinder were found to have some specific behavior in each case.
