Conclusions

  1. 1.

    During discharge of a flow from a cone valve at small heads E0/hv≤1.2, when the upper part of the jet falls on its lower part, the maximum velocities are observed in the center of the flow, and when E0/hv>1.2 their maximum values shift toward the side walls, which can lead to erosion of the banks in the lower pool of the structures.

     
  2. 2.

    Experimental dependences were obtained for determining the conjugate depths in the lower pool beyond the cone valves with free discharge of the flow into the atmosphere.

     
  3. 3.

    The proposed efficient structures for dissipating the excess energy of the flow beyond cone valves make it possible to distribute the unit discharges over the width of the lower pool and to avoid dangerous erosion of the bottom and banks of the river channel.
