Importance of knowing air entrainment in flows from high spillways
Air entrainment refers to the process of air being mixed with water as it flows down a spillway. It is important to know the air entrainment in flows coming down from very high spillways for the following reasons:
1. Design of efficient side walls and energy dissipators
Air entrainment can lead to high levels of turbulence in the flowing water, which can cause erosion and damage to the side walls of the spillway. By knowing the level of air entrainment, engineers can design efficient side walls and energy dissipators that can withstand the high levels of turbulence.
2. Design of vibration-free crest gates
Air entrainment can also cause vibration in crest gates, which can result in damage and malfunctioning. By understanding the level of air entrainment, engineers can design crest gates that are vibration-free and can operate smoothly.
3. Determination of the coefficient of discharge of the spillway
The coefficient of discharge is a measure of the efficiency of a spillway in discharging water. The presence of air can affect the flow characteristics of the water and alter the coefficient of discharge. By knowing the level of air entrainment, engineers can accurately determine the coefficient of discharge of the spillway.
4. Determination of the roughness characteristics of the spillway
Air entrainment can also affect the roughness characteristics of the spillway. The presence of air bubbles can create a rougher surface, which can affect the flow of water and cause erosion. By understanding the level of air entrainment, engineers can accurately determine the roughness characteristics of the spillway and design it accordingly.
In conclusion, knowing the air entrainment in flows coming down from very high spillways is crucial for designing efficient side walls and energy dissipators, vibration-free crest gates, and determining the coefficient of discharge and roughness characteristics of the spillway.
