  1. 1.

    Hydraulic investigations of an energy dissipation chamber in which dissipation is accomplished by the splitting and collision of flows with their simultaneous aeration indicate its high energy-dissipating capacity.

  2. 2.

    The dissipation chamber is simple in design and permits dissipating up to 95–97% of the initial store of energy with an intensity of energy dissipation greater than 60–65 kW/m3.

  3. 3.

    Generalization of the available data permitted outlining a method of approximate hydraulic calculation of the dissipation chamber.

  4. 4.

    A circular dissipation chamber has now been designed by Sredazgidroproekt for the drinking-water intake of the city of Angren.

    The projects of the Uzbek Planning, Surveying, and Scientific Research Institute of Water-Management Construction call for installing square dissipation chambers at the following hydrodevelopments: Zaamin (Qmax=40 m3/sec, Hmax=60 m), Sokh (Qmax=25 m3/sec, Hmax=90 m), Tupolang (Qmax=70 m3/sec, Hmax=170 m), Gissar (Qmax=34 m3/sec, Hmax=136 m).

  5. 5.

    It is necessary to conduct further investigations, the main tasks of which should be: a) establishment of a reliable relation between the discharge of air used for aeration of the flow and the parameters of the flow being discharged through the cone valve into the flow parameters and hydrodynamic forces being absorbed by components of the dissipation chamber; c) refinement of the relation between the dissipation coefficient, on the one hand, and the flow parameters and geometry of the dissipation chamber of the other.
