Processes of energy exchange in a gravitational suspension flow have been experimentally studied. An equation for the transfer of the potential energy of solid particles has been derived. The anisotropy of pulsatory motions in the flow has been observed, and the possibility of turbulence production upon breakage of structures with an unstable stratification has been shown. Some peculiarities of flow motion in the regime of negative turbulent viscosity are discussed.
