摘要:

Flows with coherent structures allow see‐free measurements of local velocity and velocity fluctuations. Continuous turbulent velocity histories in ionizing shock waves are obtained at a 10‐MHz sampling rate. From this, correlation profiles and frequency spectra are determined which reveal the presence of prominent high‐frequency components.
