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

SGER：曲流河道非均匀输沙的综合实验与数值模拟研究[j]：段国红，美国亚利桑那大学土木工程系。摘要：本研究拟采用实验与数值相结合的方法，研究曲流弯道沉积物的运移与分选。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生成的曲流水槽和购买脉冲相干声速分析器。实验将对水槽内的湍流流场进行测量。同时，PI将获得FLUENT用户许可证，并在新购买的计算机服务器上安装和测试。研究小组还将对曲流河流的流体动力学和泥沙输运研究进行深入的文献综述。第一年后，预计基本设施（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
