Аннотация:
The two-beam interferometry and luminescence methods are used to measure the spatial and time characteristics of fluctuations of subsonic turbulent flow of molecular gas in a strong oscillatory nonequilibrium state. A gas discharge tube of a CO2 laser with fast axial pumping is the object under treatment. The turbulent component of fluctuation of the gas density is selected by the frequency selection of the recorded signal. The spectrum of the density fluctuations and the dependence of the amplitude of pulsations of small-scale nonuniformities on the energy input is determined. Further, the degree of cross correlation between fluctuations of the phase incidence of the wave front in turbulent flow is measured under nonequilibrium conditions of electric discharge. © 1999 MAEe cyrillic signK "Hayκa/Interperiodica".
