Abstract
Experimental study of the propagation of high-frequency acoustic waves in grid-generated turbulence in laboratory conditions by means of ultrasound technique is considered. The travel time and log-amplitude variance of acoustic waves are investigated as functions of travel distance and mean velocity. Experimental data were interpreted using theoretical analysis based on ray acoustics and Rytov approximation. The travel time shift in acoustic wave propagation in turbulent and undisturbed media is observed.
