Wang, Guangqian 王光谦

Dr. Guangqian Wang is a professor and general director of the State Key Laboratory of Hydroscience and Engineering, Tsinghua University in China. He was a winner of the National Outstanding Younger Fund Award in 1995 and got financial supports from the Strategic Research Fund of National Natural Science Foundation in 2002. Currently, he is the chief scientist of the National Basic Research Program of China. He is a vice director of Landslide and Debris Flow Committee of the Chinese Society of Water and Soil Conservation, and a vice director of the Sediment Committee of Chinese Hydraulic Engineering Society. Professor Wang’s main research achievements include: (1) developing a kinetic model and obtaining corresponding theoretical solution for solid-liquid two-phase flows with low sediment concentrations. The developed kinetic model was used to successfully explain the phenomenon that the maximum sediment concentration does not located at the bottom of water for the type I distribution and to overcome the shortcomings that the calculated sediment concentration was zero at water surface and that it was infinite at bottom from the Rouse formula. With the achievements, Prof. Wang was awarded the Ning Chien Memorial Prize in 1992; (2) developing of a kinetic model for solid-liquid two-phase flows with high sediment concentrations based on revised BGK collision operators, and establishing constitutive relations of particles movements. With the achievement Prof. Wang received the excellent paper award by the World Association for Sedimentation and Erosion Research in 2007; (3) developing the granular flow model for debris flow and establishing the constitutive relations of granular mass flows as well as determining the volumetric concentration threshold for judging relative importance between granular fluctuating stress and collision stress. The results were used as the criterion for judging significance of granular collision effect; (4) developing a digital watershed model through integrating multiple hydrologic, hydrodynamic and sedimentation dynamic processes. Sedimentation and erosion modeling methodologies for river basins were initiated; (5) Applications of the developed methodologies and models to many momentous projects, such as construction of the Three Gorges Project, operation of the Sanmenxia Reservoir in the Yellow River Basin, water resources regulation in the Yellow River Basin, have resulted in significant contributions. Professor Wang has been awarded several national-level prizes for his achievements in science and engineering fields. He has published more than 150 journal papers and 4 books in areas of river mechanics, digital watershed modeling and water resource information system.

王光谦 教授, 清华大学 1962年4月生，1982年毕业于武汉水利电力学院，1989年在清华大学获博士学位，现为清华大学水电工程系教授。他对固液两相流尤其是泥沙运动和泥石流进行了较深入的研究，解决了泥沙运动中的一些重要问题。如悬移质浓度垂向分布的类型，并探讨其成因，得到泥沙浓度的统一公式。他所进行的快速颗粒流研究，在高含沙流、泥石流以及固料输运等方面有广泛的应用。 同时他还发展了固液两相流的新的双流体模型，对固液两相流基本理论及其应用加以总结。他不仅在学术上有所成就，而且在承担重点工程课题中，解决生产问题表现突出。他参加了三峡坝区泥沙模型试验，为1994年7月三峡工种设计审查提供了依据。他先后发表论文40多篇，并著《固液两相流基本理论及其应用》一书。他的科研成果得到了国内外同行的好评，一些成果已达到国际先进水平。曾获钱宁泥沙科学论文奖，周培源优秀水动力学论文一等奖。霍英东青年教师基金。
