Acquisition of High-Speed Camera and Instrumentation for Flow Visualization and Measurement

摘要建议编号 CTS-0320634主要研究者： J. Rossman，Harvey Mudd学院PI正在Harvey Mudd学院建立一个实验流体力学实验室。2002年夏天，亚音速风洞设施开始建设，所有的设计决策都是由大学生研究人员在PI的指导下做出的。该设备可用于研究各种外部流动。它的限流仪表包括一个皮托静压探头和一个热线风速计。根据赠款购买的流动可视化设备将通过增加压敏涂料以及高速视频速率和静态摄像系统来显着提高该设施的能力。该设备将使复杂的流体动力学，包括曲线球和鸟的翅膀，在高分辨率的视觉定性和定量研究，并将显着扩大我们的学生的接触和实验技术和仪器的培训。该摄像机系统也将对哈维·穆德学院和克莱蒙学院联盟的其他教师正在进行的研究非常有用，用于从液滴形成和动力学到蜥蜴生物力学的项目。以下设备将根据赠款获得：（1）高分辨率CCD相机，包括来自罗珀科技公司的镜头、PCI卡和软件，（2）高速Phantom CMOS相机，包括来自视觉研究公司的PCI卡和软件，（3）压敏涂料（PSP）套件，包括ISSI的LED光源和数据采集和处理软件，以及（4）具有足够图像处理内存的个人计算机和彩色打印机。这些设备将对几个研究项目产生巨大的积极影响，也许更重要的是，哈维穆德学院本科生的研究训练该设备将使用两台最先进的摄像机和PSP技术为这些学生提供特殊的研究和培训机会，进一步实现学院为所有学生提供实质性和有意义的研究机会的目标。

ABSTRACTProposal No. CTS-0320634Principal Investigator: J. Rossman, Harvey Mudd College The PI is establishing an experimental fluid mechanics laboratory at Harvey Mudd College. In the summer of 2002, construction began on a subsonic wind tunnel facility for which all design decisions were made by undergraduate researchers with guidance from the PI. This facility may be used to study a wide variety of external flows. Its limited current instrumentation consists of a Pitot-static probe and a hot-wire anemometer. The flow visualization equipment acquired under the grant will significantly increase the capabilities of this facility by adding pressure-sensitive paint as well as a high-speed video-rate and still camera system. This equipment will enable visual qualitative and quantitative study of complex fluid dynamics, including those of curveballs and bird wings, at high resolution, and will significantly expand our students' exposure to and training in experimental techniques and instrumentation. This camera system will also be extremely useful to the ongoing research of other faculty at Harvey Mudd College and in the Claremont Colleges Consortium, for projects ranging from droplet formation and dynamics to lizard biomechanics.The following equipment will be acquired under the grant:(1) High-resolution CCD camera, including lenses, PCI card and software from Roper Scientific, (2) High-speed Phantom CMOS camera, including PCI card and software from Vision Research, (3) Pressure-sensitive paint (PSP) kit, including LED light source and software for data acquisition and processing, from ISSI, and (4) Personal computer with sufficient memory for image processing, and color printer.The equipment will have a tremendously positive impact on several research projects, and perhaps even more significantly, on the research training of Harvey Mudd College undergraduates. This equipment will provide exceptional research and training opportunities for these students using two state-of-the-art cameras and the PSP technique, furthering the College's goal of providing substantial and meaningful research opportunities for all of its students.
