I-Corps L Compressible Flow Water Table

加州大学戴维斯分校（UC Davis）开发的学习创新包括内部建造的地下水位，相关的机翼模型和教育材料。该项目打算将创新扩展到高中、社区学院和大学教育。水力学上的类比是在有自由表面的水流和二维可压缩气流之间进行的。地下水位所展示的水力类比概念不仅可以作为飞机机翼的类比，还可以作为火箭喷嘴、风力涡轮机和许多其他流动相关现象的类比。这个实验是基于一个众所周知的类比，将可压缩的二维空气流中的波与平面上浅水层的表面波进行类比。这一创新将在课程中用于向学生演示使用廉价工具的水力类比。这个项目的假设是，地下水位是一个有用的发明，以加强高中和社区大学的教育。该假设将通过对相关和潜在客户进行100次访谈来验证。通过动手实验参与主动学习的学生通过自我发现来学习。这将吸引学生学习工程和科学，并提供持久的学习经验。系统地，他们学会改变他们对物理现象的假设，并发现潜在的概念。这种教学方式将培养学生的批判性思维，并有效地使他们参与课堂。该团队不仅希望在加州大学戴维斯分校广泛使用该工具，还希望其他教育机构也能采用这种方法。

The learning innovation developed at the University of California Davis (UC Davis) includes an in-house built water table, relevant wing models, and educational material. The project intends to scale the innovation to high school, community college and university education. The hydraulic analogy is between water flow with a free surface and two-dimensional compressible gas flow. The concept of hydraulic analogy demonstrated in the water table can serve as a great analogy not only for airplane wings but also rocket nozzles, wind turbines and many other flow related phenomena. The experiment is based on a well-known analogy between waves in compressible two dimensional flow of air to the surface waves of a shallow water layer over a flat surface. The innovation will be used in the course to demonstrate to students the hydraulic analogy using inexpensive tools. The hypothesis of this project is that the water table is a useful invention to reinforce high school and community college education. The hypothesis will be tested by conducting 100 interviews with relevant and potential customers. Students who participate in active learning with hands-on experiments learn through self-discovery. This will attract students to engineering and science and provide lasting learning experiences. Systematically, they learn to change their presumptions about the phenomena in physics and discover the underlying concepts. This way of teaching will develop critical thinking among students and effectively engage them in classrooms. The team expects not only to use this tool broadly at UC Davis, but anticipates that other educational institutes will adopt this method.
