Simulation of the load rejection transient process of a francis turbine by using a 1-D-3-D coupling approach被引量：15
《Journal of Hydrodynamics》2014年第5期715-724,共10页张晓曦 程永光 杨建东 夏林生 赖旭 
supported by the National Natural Science Foundation of China(Grant Nos.51039005 and 50909076)
This paper presents the simulation and the analysis of the transient process of a Francis turbine during the load rejection by employing a one-dimensional and three-dimensional （1-D-3-D） coupling approach. The coupl...

3-D simulation of transient flow patterns in a corridor-shaped air-cushion surge chamber based on computational fluid dynamics被引量：3
《Journal of Hydrodynamics》2013年第2期249-257,共9页夏林生 程永光 周大庆 
support by the National Natural Science Foundation of China(Grant Nos.51039005,50909076)
The 3-D characteristics of the water-air flow patterns in a corridor-shaped air-cushion surge chamber during hydraulic transients need to be considered in the shape optimization. To verify the reliability of the water...

SIMULATION OF HYDRAULIC TRANSIENTS IN HYDROPOWER SYSTEMS USING THE 1-D-3-D COUPLING APPROACH被引量：24
《Journal of Hydrodynamics》2012年第4期595-604,共10页ZHANG Xiao-xi CHENG Yong-guang 
the National Natural Science Foundation of China (Grant Nos. 51039005, 50909076)
Although the hydraulic transients in pipe systems are usually simulated by using a one-dimensional （l-D） approach, local three-dimensional （3-D） simulations are necessary because of obvious 3-D flow features in so...
