Abstract
A new method is used to generate a quasihomogeneous isotropic turbulent supersonic flow at Mach number 3. The interaction with a normal shock wave is analyzed by means of hot-wire anemometry and laser Doppler velocimetry. Preliminary results show that the usual behavior of unperturbed turbulence is observed (isotropy, spectra, integral scales, and decay). The shock wave increases the longitudinal fluctuating velocities in agreement with Ribner's theory. Increase of the high-frequency components and decrease of the integral longitudinal scales are observed at the traverse of the shock.
