SGER: Preliminary Investigation of Flow and Non-uniform Sediment Transport in Meandering Channels

曲折河道非均匀输沙综合试验与数值模拟研究PI：段国宏，大学土木工程系。第一年的支持摘要：这项拟议的研究是将实验和数值方法相结合，以研究通过曲折的泥沙输送和分类。第一年的目标是建立基本的实验和数值模拟设施。具体任务包括建造一个正弦产生的曲折水槽，并购买一台脉冲相干声速剖面仪。对该水槽内的湍流流场进行了实验测量。与此同时，PI将获得流畅的用户许可证，并在新购买的计算机服务器上安装和测试。研究小组还将进行密集的文献综述，重点是蜿蜒溪流中的水流流体动力学和泥沙运动研究。第一年后，预计必要的设施(如水槽、PCAVP)将准备好进行进一步的实验和计算

SGER: Integrated Experimental and Numerical Modeling Study of Non-uniform Sediment Transport in Meandering ChannelsPI: Jennifer Guohong Duan, Department of Civil Engineering, Univ. of Arizona.Abstract for the first year support:This proposed research is to integrate experimental and numerical methods to investigate sediment transport and sorting through meandering bends. The objective of the first year effort is to set up basic experimental and numerical modeling facilities. The specific tasks include constructing one sine-generated meandering flume and purchasing a Pulse Coherent Acoustic Velocity Profiler. Experiments will be performed to measure turbulent flow field in this flume. In the meantime, the PI will acquire FLUENT user license and install and test it in a newly purchased computer server. The research team will also conduct an intensive literature review focusing on flow hydrodynamics and sediment transport studies in meandering streams. After the first year, it's expected that the essential facilities (e.g. flume, PCAVP) will be ready for performing further experimental and computational mo
