CTS-0078926 F. Ting, South Dakota State Universty AbstractThe 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. 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 very useful for testing a wide range of modeling techniques, including both present day models and models that are under long-range development.The requested precision-tilting flume will be an important contribution to the modernization of the Fluid Mechanic Laboratory at South Dakota State University. This laboratory is used cooperatively by all deparments 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 a researcher 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 investigations 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. 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 requested equipment.

在不久的将来，将使用CTS-0078926 F. Ting。改善了码头和断裂波的湍流的描述对于开发用于码头冲刷和沿海过程的准确有效的计算方法至关重要。拟议的研究还将提供测试和改善桥梁码头流和冲浪区流体动力学详细模型所需的高质量数据。该数据集将远远超出目前可用的任何可比数据集，并且对于测试广泛的建模技术非常有用，包括当今的模型和远程开发的模型。倾斜水槽将是南达科他州立大学流体机械实验室现代化的重要贡献。该实验室由工程学院的所有dar仪协同使用。此外，我们在南达科他州矿业与技术学院合作机构的合作计划还将利用所需的水槽进行研究和教育。这种用途将得到增强，因为远程操作系统将使研究人员能够通过Internet运行水槽并通过计算机获取仪器数据。因此，收购要求的水槽将允许南达科他州的教职员工进行竞争性调查，并更有效地争夺研究资金。研究支持量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。研究和教学的整合将为南达科他州的学生提供提高的教育质量。此外，基于Internet的远程远程访问将增强多样性，并将使机构（例如部落大学，两年学院和高中）没有流动的机械师实验室来参与所需设备支持的项目和活动。
