Using Computing and Modern Measuring Equipment in Undergraduate Fluid Mechanics Experiments

该项目实施了一个现实的，廉价的计划，使用计算和现代测量设备在实验设计的土木工程本科流体力学实验室课程。在此之前，基本概念和流体力学中的重要现象的实验室研究和实验流体力学和水力学的本科生发展一直受到缺乏现代仪器的阻碍。通过购买用于测量明渠流速的声学多普勒流速计、用于测量管流水头损失的差压传感器以及用于数据收集和显示的两个基于PC的数据采集系统，可以解决这个问题。该设备用于开发六个新的实验（加速度场，线动量守恒，水跃，湍流剪切应力，沿沿着管的摩擦损失，和数据采集的基础）。 这些实验可以更好地理解流体力学原理，并为本科生提供现代设备的经验。由于实验装置和程序简单实用，实验可以很容易地在类似的机构进行调整。测试结果和学生的评价，可以得到评估该项目的影响，本科学习流体力学原理和现代实验室技术。发展计划和成果评估可以通过在美国工程教育学会（ASEE）年度会议论文集上发表来传播。实验也可以记录在流体力学实验室手册中，该手册将在南达科他州州立大学当地出版。

This project implements a realistic, inexpensive plan for using computing and modern measuring equipment in experiments designed for a civil engineering undergraduate fluid mechanics laboratory course. Previously, the laboratory study of basic concepts and significant phenomena in fluid mechanics and the undergraduate development in experimental fluid mechanics and hydraulics have been hampered by a lack of modern instrumentation. With the purchase of an Acoustic Doppler Velocimeter for measuring flow velocity in open channels, a differential pressure transducer for measuring head loss in pipe flows, and two PC-based data acquisition systems for data collection and display, this problem can be remedied. The equipment is used in developing six new experiments (acceleration field, conservation of linear momentum, hydraulic jump, turbulent shear stress, friction loss along a pipe, and fundamentals of data acquisition). These experiments allow for a better understanding of fluid mechanics principles and give undergraduates experience with modern equipment. Because the experimental setup and procedures are simple and practical, experiments may be readily adapted at similar institutions. Test results and students' evaluations can be obtained to assess the impact of this project on undergraduate learning of fluid mechanics principles and modern laboratory techniques. The development plan and the outcome assessment can be disseminated through publication in the American Society for Engineering Education (ASEE) Annual Conference Proceedings. Experiments can also be documented in a Fluid Mechanics Laboratory Manual to be published locally at South Dakota State University.
