WATER FLOW ENERGY DISSIPATOR Russian patent published in 2017 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: water flow energy dissipator comprises a water duct 1, pressure lines 2 connected tangentially to the surface of annular chambers 3. Between the annular chambers 3 a diamond-shaped transition chamber 6 is located which is connected through the input slots 5 to the annular chambers 3. The diamond-shaped chamber 6 has an outlet 7 connecting the expanding pressure section 8 of the pipeline with the confuser 9 with the discharge water duct 10. A part of flow with higher specific energy is supplied from the wall region of the input chamber 3 through the inlet slots into the diamond-shaped transition chamber 6, where jet flows are combined in one common flow and mutually collide, that which reduces the kinetic energy of the flow. Combined, mixed, and dissipated flow gets the third stage energy of dissipation at the conjunction of the pressure 8 with the confuser 9 and enters the discharge water duct 10.

EFFECT: increase of efficiency and reliability of dissipation of kinetic energy, of divided and re-combined flow, reducing the dynamic loads on the structure, simultaneous flushing of all dissipation chambers from deposited sediments.
