“…It was also found that the radiation in the "cluster wake" region is observed only on individual argon lines (Fig. 8, b), located mainly in the yellow-green part of the spectrum, which is consistent with the previously discovered effect of anomalous amplification of radiation initiated in clustered flows [24]. To clarify the conditions for the appearance of luminescence in the "cluster wake", measurements were made of the average lifetime of flow particles in an excited state τ [21].…”

In this work, the influence of the cluster formation process on the gas dynamics of a supersonic flow is studied by the method of electron-beam visualization. Corrections to the model for describing the transverse dimensions of supersonic flows under conditions of developed condensation are presented. Possible causes and conditions for the formation of a secondary cocurrent flow are analyzed. The influence of background gas penetration into the clastered flow has been studied. The conditions for the occurrence of an anomalous afterglow of a clastered flow upon initiation by an electron discharge are studied.

“…The diagnostics of ions internal states were carried out by the electronicvibrational-rotational spectrum of their spontaneous emission. The damping constant A 2 S + (v'=2) of the vibrational state of the HF + ion by helium atoms was measured [27]. During the vibrational relaxation of the excited states of HF + ion, a part of the energy is transferred to the rotational degrees of freedom.…”

A review of the experimental work carried out on the vacuum gas-dynamic stands of the Applied Physics Department of the Novosibirsk State University is presented. Creation of these stands meeting the world’s requirements and equipped with modern diagnostic methods was based on the background experience from the Institute of Thermophysics of the Siberian Branch of the Russian Academy of Sciences under the guidance of A.K. Rebrov. A brief description of the stands and the results of some studies is given. Despite the limited possibilities of the university environment, the use of compact laboratory vacuum stands provides large-scale studies in various areas of rarefied gas dynamics.
