Transient air-water flow patterns in the vent tube in hydropower tailrace system simulated by 1-D-3-D coupling method被引量：3
《Journal of Hydrodynamics》2018年第4期715-721,共7页王希晨 张健 俞晓东 陈胜 
Project supported by the National Key R&D Program of China(Grant No.2016YFC0401810);the Research Project of Science and Technology Commission of Shanghai Munici-pality(Grant No.16DZ1202205);and the Fundamental Research Funds for the Central Universities(Grant No.2016B10814)
The vent tube is commonly used for the water hammer protection in the hydropower tailrace system. In transient processes, with air entering and exiting the vent tube, one sees complex hydraulic phenomena, which threat...

An axisymmetric model for draft tube flow at partial load被引量：3
《Journal of Hydrodynamics》2016年第2期195-205,共11页Hosein FOROUTAN Savas YAVUZKURT 
funded in part by the Office of Energy Efficiency and Renewable Energy (EERE), U.S. Department of Energy, under Award Numbers DE-EE0002667 (the DOE/PSU Graduate Student Fellowship Program for Hydropower Research);DE-EE0002668 (The HRF Fellowship);the Hydro Research Foundation
A new Reynolds-averaged Navier-Stokes （RANS） turbulence model is developed in order to correctly predict the mean flow field in a draft tube operating under partial load using 2-D axisymmetric simulations. It is sho...
