Abstract:

The results of experimental researches of fluctuations of the laser beam intensity extending through a supersonic flooded jet are presented. The work is executed at the stand of Institute of applied and theoretical mechanics of the Siberian Branch of the Russian Academy of Science. The laser beam passed across a jet on various distances from Vitochinskogo nozzle. The experiment was spent at pressure in Ejfelja chamber from 1,7 up to 7 at two modes of the expiration of a jet: with the use of chevrons on the day off nozzle and without chevrons. Dependences of a dispersion and spectra of fluctuations on pressure and distances from the nozzle are found. The internal optical scale of the turbulence is estimated.
