1. Spillway flow behaviours with and without aeration
University essay from KTH/Teknisk mekanikAbstract : Cavitation has been known for a long time to cause damages in spillways athydropower plants, aerators are therefore often implemented to prevent this.The majority of the hydropower plants in Sweden are installed in the northernpart of the country.

2. Experimental Investigation Of The Air-Water Flow Properties In The Cavity Zone Downstream A Chute Aerator
University essay fromAbstract : 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. Layout of spillway aerator air ventsand its effect on air supply
University essay from KTH/MekanikAbstract : 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. CFD modelling of dam spillway aerator
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : The purposes of this master thesis are the simulation of the aerator air flow driven by the spillway water flow in the Bergeforsen dam and the behavior of the flow in the stilling basin. Aerators are employed to supply air at critical locations in the flow where low pressure and cavitation may occur in order to protect the structure. READ MORE

5. Design of aerators for prevention of cavitation – The Höljes Dam.
University essay from KTH/VattendragsteknikAbstract : 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
