series of experiments using correlation and spectral analysis has been performed to study the spatial structure of a liquid, in which turbulence is set by a vibrating grid. The experiments have shown that there are three regions of motion in such a liquid: jet flow, transition, and random (turbulent) zones. Turbulence intensity in pure water and in suspension has been estimated and the vertical scale of turbulent formations has been determined. In suspension, part of turbulent energy of a liquid is absorbed by suspended particles.
