Flow Measurements in Ocean Engineering Undergraduate Laboratories

该项目通过安装激光多谱勒风速计流动系统和建造新的波箱来提高学生测量流体运动的能力。在流体力学实验室，介绍了激光在测量领域的应用。该设备使学生能够测量不同流动的速度分布。激光多普勒测速仪可以集中测量流体流动中的速度和湍流，而不会干扰流体颗粒的运动。实验说明了流动分离、失速、旋涡脱落、阻力计算、湍流和剪切力等概念。当学生完成流体力学实验室后，他们准备扩展他们的能力，使用新的波浪水槽对沿海环境中的流动现象进行更多的实验。

This project enhances the student's ability to measure fluid motion by the installation of a laser doppler anemometer flow system and by the construction of a new wave tank. In the fluid dynamics laboratory, an introduction to the application of lasers in the field of measurements is presented. The equipment enables the students to measure the velocity profiles for different flows. The laser doppler velocimeter allows a focused measurement of velocity and turbulence in fluid flows, without disturbing the movement of the fluid particles. Experiments illustrate such concepts as flow separation, stall, vortex shedding, drag calculation, turbulence, and shear stress. When students finish their fluid dynamics laboratory, they are ready to expand their capability to conduct more experiments on flow phenomena in the coastal environment using the new wave flume.
