Enhancement of density turbulent fluctuations following the passage of а shock wave, turbulence scale, and also the correlation and spectral functions of fluctuations in the wake and ahead ofthe wave has been studied theoretically and experimentally in this paper. The calculations are based on the Euler equations, and turbulence is modeled bу а packet of velocity pulses. Experiments were conducted in а single-diaphragm shock tube, and turbulence was produced bу means ofa wire mesh. Jhe Mach number values were taken in the range ofl.1-3 in the shock-wave calculations and 1.35-1.6 in the experiments. The theoretical data are in good agreement with experimental results.
