项目摘要

The primary goal of the work is to involve undergraduate students in original scientific research and introduce them to the excitement and challenge that a profession in the sciences offers. The research encompasses a study that will lead to an understanding of the airflow in resonating pipes of different geometries. The emphasis is on understanding the flow through pipes with different shapes coupled to oscillations caused by an air jet interacting with a sharp edge. The system used to study this interaction will be the organ pipe. However, the results can be used to understand the many scientific and industrial situations that involve oscillating or flowing air contained within a metal or wooden duct. As part of the work, a method for optically imaging gas and fluid flow over a large area will be developed and optimized for imaging airflow at room temperature. Additionally, a computer simulation will be developed and validated with the experimental results so that the effects of changing the physical parameters of the pipe can be investigated theoretically. A significant effort will be made to recruit women students to participate in enhancing the participation of women pursuing scientific research as a career.The work involves collaborating with undergraduate students to understand the physics of airflow in flue organ pipes and recorders. The primary goal is to involve undergraduate students in original scientific research and introduce them to the excitement and challenge that will result in a life dedicated to scientific pursuits. The scientific goal is to understand the airflow in pipes of different geometries coupled to oscillations driven by a jet-edge interaction. Of particular interest are the differences in oscillating and steady-state flows with low Reynolds numbers propagating through circular and rectangular pipes. This type of system is found in fipple musical instruments such as flue organ pipes and recorders and many industrial situations. Transmission electronic speckle pattern interferometry will be used to obtain high-speed imagery of airflow through circular and rectangular transparent pipes of equal cross-sectional area produced by 3-D printing. The imagery will be coupled with pressure and flow velocity measurements to understand why the flow through rectangular organ pipes appears to differ from the flow-through cylindrical organ pipes. The experimental results will be used to validate a computer simulation, which will then be used to investigate the influence of other physical parameters on the flow through the oscillator-resonator system. The results will lead to a better understanding of the effects of the pipe shape on acoustics and fluid flow in resonators coupled to flow-driven oscillations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
这项工作的主要目标是让本科生参与原创科学研究,并向他们介绍科学专业所提供的兴奋和挑战。该研究包括一项研究,将导致对不同几何形状的谐振管道中的气流的理解。重点是了解通过不同形状的管道的流动,这些管道与由空气射流与尖锐边缘相互作用引起的振荡耦合。用于研究这种相互作用的系统将是器官管道。然而,这些结果可用于理解许多科学和工业情况,这些情况涉及金属或木制管道内的振荡或流动空气。作为工作的一部分,将开发和优化一种用于大面积气体和流体流动的光学成像方法,以在室温下对气流进行成像。此外,将开发计算机模拟并与实验结果进行验证,以便从理论上研究改变管道物理参数的影响。将大力招募女学生参与促进妇女参与科研事业的工作,这项工作包括与大学生合作,了解烟道管风琴和录音机中的气流物理。主要目标是让本科生参与原创科学研究,并向他们介绍将导致一生致力于科学追求的兴奋和挑战。科学目标是了解不同几何形状的管道中的气流,这些管道与射流边缘相互作用驱动的振荡耦合。特别令人感兴趣的是在振荡和稳态流动与低雷诺数传播通过圆形和矩形管道的差异。这种类型的系统是在fipple乐器,如烟道管风琴管和录音机和许多工业场合。透射电子散斑干涉测量法将用于获得通过3D打印产生的相等横截面积的圆形和矩形透明管道的气流的高速图像。该图像将与压力和流速测量相结合,以了解为什么通过矩形管风琴管道的流量似乎与通过圆柱形管风琴管道的流量不同。实验结果将被用来验证计算机模拟,然后将被用来调查其他物理参数的影响,对通过搅拌器谐振器系统的流量。研究结果将有助于更好地了解管道形状对声学和流体流动的影响,以及与流动驱动振荡耦合的谐振器。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
