摘要CTS-0075713 C。在不久的将来，所要求的明渠水槽将用于桥墩周围湍流场和不规则破碎波中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，以及碎波区波。改进桥墩和破碎波中湍流的描述对于发展桥墩冲刷和海岸过程的精确和有效的计算方法至关重要。拟议的研究还将提供测试和改进桥墩流和碎波区流体动力学的详细模型所需的高质量数据。 这一数据集将远远超出任何可比的数据集，目前可用的，它将是有用的，用于测试范围广泛的建模技术，包括目前的模型和模型下的长期发展在future.The要求的精密倾斜水槽将是一个重要的贡献，现代化的流体力学实验室在南达科他州州立大学。 本实验室由工学院各系共同使用。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。这种使用将得到加强，因为远程操作系统将使研究人员能够通过互联网使用计算机运行水槽并获取仪器数据。因此，收购所要求的水槽将允许南达科他州教师进行竞争性的仪器和更有效地竞争研究资金。 相应增加研究支持的数量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。 研究与教学的整合将为南达科他州的学生提供更高的教育质量。 此外，通过因特网远程访问设备将加强多样性，并使没有流体力学实验室的机构（如部落大学、两年制学院和高中）能够参加由所需设备支助的项目和活动。

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.
