Radiation Characteristics of Shock-Heated Air in the Visible and Infrared Spectral Ranges
The integral and temporal spectral characteristics of shock-heated air are measured in the shock wave velocity range from 7.35 to 10.4 km/s at the pressure ahead of the shock front p0 = 0.25 Torr. The experiments are carried out on the DDST-M shock-wave setup of the Institute of Mechanics of Moscow State University. The radiation wave range λ = 600–1100 nm is studied; it corresponds to the visible and near infrared spectral ranges, where the main contribution to the radiation is made by the atomic lines of nitrogen and oxygen. The integral-in-time radiation spectrograms obtained in the experiments are analyzed. The distinctive features of the time oscillograms are defined for the most typical atomic lines of the spectrum. The measurement data are compared with the experimental data of other authors.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
