Air-vent layouts and water-air flow behaviors of a wide spillway aerator
《Theoretical & Applied Mechanics Letters》2019年第2期130-143,共14页James Yang Penghua Teng Chang Lin 
part of research project "Hydraulic design of spillway aerators";funded in part by Swedish Hydropower Centre(SVC);Vattenfall R&D;Fortum Generation;Uniper/Sweco have indirectly facilitated the study
A spillway aerator should guarantee favorable flow conditions in the coupled water-air system even if the aerator is unconventionally wide. Eight air-vent configurations are devised and incorporated into a 35-m wide c...

THEORETICAL AND EXPERIMENTAL STUDIES OF THE FLARING GATE PIER ON THE SURFACE SPILLWAY IN A HIGH-ARCH DAM被引量：11
《Journal of Hydrodynamics》2012年第4期496-505,共10页LI Nai-wen LIU Chao DENG Jun ZHANG Xiao-zhe 
the National Natural Science Foundation of China (Grant Nos. 50909067, 51009102);the Program for New Century Excellent Talents in University (Grant No. 2011SCU-NCET-10-0589)
The experimental studies of the flaring gate pier applied on the surface spillway in a high-arch dam show that a shock-wave will appear when the pattern of the flow is kept as super-critical. Meanwhile, the water dept...

Unsteady Spillway Flows by Singular Integral Operators Method
《Engineering（科研）》2012年第3期133-138,共6页Evangelos G. Ladopoulos 
The Singular Integral Operators Method (S.I.O.M.) is applied to the determination of the free-surface profile of an un-steady flow over a spillway, which defines a classical hydraulics problem in open channel flow. Th...

RE-AERATION LAW OF WATER FLOW OVER SPILLWAYS被引量：3
《Journal of Hydrodynamics》2006年第2期231-236,共6页CHENG Xiang-ju LUO Lin CHEN Yong-can ZHAO Wen-qian 
Project supported by the National Natural Science Foundation of China (Grant No:50079013).
In order to explore the re-aeration law of water flow over spillway, the transfer process of oxygen in water flow over spillway was studied. The interfacial mass transfer coefficients were obtained by experiments. The...

RANDOM　CHARACTERISTICS　OF　FLOW　FLUCTUATING　PRESSURE　AND　DYNAMIC　RESPONSE　ON　THE　SHAFT　SPILLWAY
《Journal of Hydrodynamics》1995年第2期28-34,共7页Cui Li(Dalian University of Technology, Dalian 116023, P. R. China) 
The flow down a shaft spillway, connected with tunnel, results in nonsymmetric vortex around the axis of the shaft. The greater the nonsymmetry, the greater the pressure fluctuation and random vibration of structures....
