EFFECT OF THE FLOW VELOCITY ON THE DOWNSTREAM ENERGY ABSORBERS AND VELOCITY COEFFICIENT

As a result of designing an energy absorber in the zone of conjugation of water outlet structures of low-pressure and medium-pressure reservoirs, the stilling basin is not only under the influence of vertical hydrodynamic pressure with a variable value, but also, the disappearance of stagnation of the stilling basin can also be affected by the hydrodynamic stress arising from the force of horizontal pressure in the energy absorber . The hydraulic jump that occurs in the pool junction zone is one of the simplest energy absorbers. To increase the efficiency of this process, it is necessary to improve the hydraulic regime in the downstream of the water outlet, reshape the interface mode in the stilling basin and on the apron surface, eliminate flow disturbance, through construction of special energy absorbers in the stilling basin. These structures exert reactive (accelerating implementation), dislocation (accommodating) and distributed forces on the flow.
