Paper Abstract
The luminescence method and the method of dual-beam shear interferometry were used to perform the measurements of spatial and time characteristics of molecular gas subsonic turbulent flow fluctuations under strong vibrational non- equilibrium. Gas-discharge tubes of fast-axial-flow CO2 laser served as the investigation object. A turbulent component of gas density fluctuations has been separated by method of frequency selection of the registered signal. The spectrum of density pulsation has been determined, as well as the amplitude dependence of small-scale inhomogeneities on energy input has been specified. A degree of cross correlation of fluctuations of wave-front phase incursion in the turbulent flow has been evaluated under non-equilibrium conditions of electric discharge.
