1. 1. Experimental Investigation Of The Air-Water Flow Properties In The Cavity Zone Downstream A Chute Aerator

   University essay from

   Author : Ebba Wargsjö; Albin Hedehag Damberg; [2017]
   Keywords : Air bubble entrainment; chute aerators; aerators; air concentration; cavitation; cavitation damage; cavitation bubbles; bubble frequency; scale effects;

   Abstract : Chute aerators are widely used in spillways to avoid cavitation damage. When the water flow passes the aerator, two jets form – upper and lower jet. The purpose of this thesis has been to study the effects from the aerator by conducting experiments in a model with a flow depth large enough to ensure that the upper and lower jet remain separated.

3. 2. Layout of spillway aerator air ventsand its effect on air supply

   University essay from KTH/Mekanik

   Author : Gustav Daggenfelt; [2017]

   Abstract : Chute aerators are constructed to protect spillways from cavitation damage.They function by launching the water ow as a jet and supplying airunderneath since having air entrained into the water is an eective way tomitigate cavitation. READ MORE

4. 3. Design of aerators for prevention of cavitation – The Höljes Dam.

   University essay from KTH/Vattendragsteknik

   Author : Kristoffer Pettersson; [2012]
   Keywords : Cavitation; Spillway chute; Flow characteristics; Aeration; Aerator; Stagnation pressure;

   Abstract : Major cavitation damages can seriously endanger the stability of hydraulic structures, in worst case lead to dam failure. To remedy the effect of cavitation on spillway chutes the most common method today is aeration of the flow. Aerators introduce air to the bottom layers of the flow, enough to prevent damages to occur in the concrete lining. READ MORE
