1. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel
University essay from Uppsala universitet/Institutionen för fysik och astronomiAbstract : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. READ MORE

2. Aeration and risk mitigation for flood discharge tunnel in Zipingpu water conservancy project
University essay from KTH/BetongbyggnadAbstract : The importance of hydraulic structures has become an essential mitigating mean for floodsthat occur more often due to climate change. Thus, the importance and safety of flooddischarge tunnels has promoted further studies and experiments on the topic to mitigatedamages, such as cavitation that arise because of high speed flows.

3. Numerical Study on Hydrodynamic Characteristics of Flood Discharge Tunnel in Zipingpu Water Conservancy Project : Using RANS equations and the VOF model
University essay from Uppsala universitet/ElektricitetsläraAbstract : To avoid the large amount of damage that floods can cause, spillway tunnels are used to control water levels. To ensure the safety of water transportation through spillway tunnels, the behaviour of the water throughout the tunnel is important to know. READ MORE

4. Cavitation assessment of the Baihetan discharge tunnel – Using Computational Fluid Dynamics
University essay from KTH/VattendragsteknikAbstract : Recently it has become more common in the construction of large dams to reuse diversion tunnels as flood discharge tunnels in the final structure. These tunnels handle large flows with the characteristics of open channel flow. When such large hydrological forces act upon a structure there are several problems to be expected. READ MORE
