The Study of Inlet Section on Flow Hydraulics in Zigzag-Morning Glory Spillways with Physical Modelling
Morning glory spillway is one of the spillways that used to passing of flood from high to low level. This spillway is used in the reservoir dams that are placed in narrow valleys and in many locations with high slope in reservoir walls. In the Morning glory spillways, the vortex flow can reduce discharge, discharge coefficient and the performance of spillway. The zigzag spillway, as another typ...
متن کاملEffect of Deflector and Aeration On the Discharge Coefficient of Submerged Flow of Morning Glory Spillways
Spillways are responsible for draining floods in dams. However, morning glory spillways are considered as free spillway type. In floods, a submerged flow is formed in their crest. This factor leads to severe pressure fluctuations in the shaft, suction and vibration of the structure and also reduces the spillway efficiency. Insufficient knowledge of the hydraulics of the submerged flow will be a...
متن کاملNumerical Study on Effect of Vertical Shaft Geometry on Seismic Responses of Morning Glory Spillways Case Study: Alborz Dam
Morning Glory Spillways are an important type of flood evacuation systems. According to the specific hydraulic and structural conditions, the evaluation of the seismic behavior of these kinds of spillways could be more precise with considering the interaction of the solid-water-foundation system. In this research, a three dimensional modeling of the morning glory spillway was conducted, conside...
متن کاملThe effect of the vortex barker and stepped chamber hydraulic flow through morning glory spillway
In recent decades, many dams have been built or are under construction. Due to the high demand for water and soil erosion, increasing the need for dam construction in different regions are quite tangible. In 1900 the number of large dams, did not exceed 50. But in the 1950s to 1986 the number of large dams (over 15 meters), more than 39,000 were counted. The 70s dams has been increasing develop...
متن کاملNumerical Study Scour Pattern on Channel Bend Using Flow-3D Software
In nature, a direct route to the river is uncommon. Most rivers have channels that bend wherea complex scour pattern dominates. We have intended to study the behavior patterns necessary to scour a river known as the dominant bends. Numerical models are powerful instruments for the prediction of such areas and can provide a good understanding of these areas. In the present study we have used a t...
