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

SGER：综合实验和数值模拟研究非均匀泥沙输移在曲折弯道PI：詹妮弗Guohong段，土木工程系，亚利桑那大学。第一年的支持摘要：本研究拟整合实验和数值方法，调查泥沙输移和分选通过曲折弯道。 第一年的目标是建立基本的实验和数值模拟设施。具体的工作包括建造一条正弦曲线弯曲水槽和购买一台脉冲相干声速剖面仪。 在此水槽中进行紊流流场量测实验。与此同时，PI将获取FLUENT用户许可证，并在新购买的计算机服务器上安装和测试。研究小组还将进行深入的文献综述，重点是曲流水流动力学和泥沙输运研究。 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
