AbstractCTS-0075713C. Mei, MITThe requested open-channel flume will be used, in the immediate future, for experimental studies of turbulent flow fields around bridge piers and the dynamics of turbulence in irregular breaking waves. This research will be fundamentally useful in its revelation of basic flow properties around bridge piers in rivers, and in surf zone waves. Improved descriptions of turbulent flows at piers and in breaking waves are critical to the development of accurate and efficient computational methods for pier scour and coastal processes. The proposed research will also provide the high quality data needed to test and improve detailed models of bridge-pier flows and surf zone hydrodynamics. This data set would go far beyond any comparable data set that is presently available, and it would be useful for testing a wide range of modeling techniques, including both present day models and models that are under long-range development in the future.The requested precision-tilting flume will be an important contribution to the modernization of the Fluid Mechanics Laboratory at South Dakota State University. This laboratory is used cooperatively by all departments in the College of Engineering. In addition, cooperative programs at our collaborating institution at South Dakota School of Mines and Technology will also utilize the requested flume for research and education. Such use will be enhanced because a remote operation system will enable researchers to run the flume and acquire instrumental data by computer through the Internet. Acquisition of the requested flume will therefore permit South Dakota faculty to carry out competitive instrumentation and more effectively compete for research funding. The corresponding increase in the amount of research support will enable South Dakota to attract and support capable graduate students and to provide research-training opportunities to undergraduate students. The integration of research and teaching will provide elevated education quality for South Dakota students. Furthermore, Internet-based remote access to equipment will enhance diversity and will enable institutions (e.g. tribal universities, two-year colleges and high schools) that do not have a Fluid Mechanics Laboratory to participate in projects and activities supported by the requested equipment.

摘要CTS-0075713C。MIT所要求的明渠水槽将在不久的将来用于桥墩周围的湍流流场和不规则破碎波中的湍流动力学的实验研究。这项研究将从根本上有助于揭示河流中桥墩周围的基本流动特性，以及冲浪区的波浪。对于桥墩冲刷和海岸过程的准确和有效的计算方法的发展，改进对桥墩和破碎波中的湍流流动的描述是至关重要的。拟议的研究还将提供所需的高质量数据，以测试和改进桥墩流动和冲浪区水动力的详细模型。这个数据集将远远超过目前可用的任何可比数据集，它将有助于测试广泛的建模技术，包括目前的模型和未来正在进行长期开发的模型。所要求的精密倾斜水槽将对南达科他州立大学流体力学实验室的现代化做出重要贡献。这个实验室由工程学院的所有院系共同使用。此外，我们在南达科他州矿业与技术学院的合作机构的合作项目也将利用所要求的水槽进行研究和教育。这种用途将得到加强，因为远程操作系统将使研究人员能够运行水槽，并通过计算机通过互联网获取仪器数据。因此，获得所要求的水槽将使南达科他州的教职员工能够进行竞争性的仪器设备，并更有效地竞争研究资金。研究资助额的相应增加将使南达科他州能够吸引和支持有能力的研究生，并为本科生提供研究培训机会。研究和教学的结合将为南达科他州的学生提供更高的教育质量。此外，通过互联网远程访问设备将增强多样性，并将使没有流体力学实验室的机构(例如部落大学、两年制学院和高中)能够参与由所需设备支持的项目和活动。
