Aeration performance of high-head siphon-shaft spillways by CFD models
(Sprınger Heıdelberg, 2021)
Siphon-shaft spillways are constituted by covering above a shaft spillway with a hood that creates siphonic pressure. This study focused on the aeration the flow through the aerator holes placed on the hood to prevent ...
Numerical modeling of spillway aerators in high-head dams
(Sprınger Heıdelberg, 2020)
Due to high flow velocity, the spillway surfaces of high-head dams can expose to cavitational damage. The most effective and economical method of protection from this damage is aerated to flow using aerators. In this study, ...
Investigation of aeration performance of Ilsu Dam outlet using two-phase flow model
(Sprınger Heıdelberg, 2019)
Cavitational damage is very important for huge hydraulic structures exposed to high flow velocities. The most effective solution to avoid this damage is to mix air into the flow through an aerator device. The conventional ...
Closure to Experimental and CFD Analysis of Circular Labyrinth Weirs by Omer Bilhan, M. Cihan Aydin, M. Emin Emiroglu, and Carol J. Miller

Experimental and CFD Analysis of Circular Labyrinth Weirs
(Asce-Amer Soc Cıvıl Engıneers, 2018)
Labyrinth weirs present an effective solution for high discharge efficiency in space-restrictive situations. However, these weirs exhibit negative effects (vibrations, noise, and instability) when the nappe clings to the ...
Closure to Prediction of Discharge Capacity over Two-Cycle Labyrinth Side Weir Using ANFIS by M. Cihan Aydin and Korhan Kayisli
(Asce-Amer Soc Cıvıl Engıneers, 2017)
Antivortex Effects on Two-Cycle Trapezoidal Labyrinth Side Weirs
(Asce-Amer Soc Cıvıl Engıneers, 2017)
Labyrinth side weirs can be preferred for the weirs with same opening instead of the other conventional side weirs. However, the vortex occurring in the cycles of the labyrinth side weirs usually obstruct to overflow in ...
Prediction of Discharge Capacity over Two-Cycle Labyrinth Side Weir Using ANFIS
(Asce-Amer Soc Cıvıl Engıneers, 2016)
Physical and mathematical models widely used in hydraulic engineering are not always effective in practice. Numerical methods such as the adaptive neuro fuzzy inference system (ANFIS) can be quite useful for estimating the ...
New Approach for Estimation of Rectangular Side Weirs Discharge in Subcritical Flow
(Asce-Amer Soc Cıvıl Engıneers, 2016)
Side weirs are used to divert the flow from a main channel to a desired environmental area. These basic hydraulic elements are commonly preferred in drainage and irrigation systems of surface water. Many studies have been ...
