Acquisition of PIV System for Study of Biological Flows

建议没有。主要研究者：Jennifer S. Rossman, Lafayette college（拉法叶学院）：获取用于生物流动研究的PIV系统这项主要研究仪器拨款用于获取粒子图像测速系统进行实验，以补充PI正在进行的动脉瘤和动脉粥样硬化影响血管流动的数值分析。PIV系统由一个Nd:YAG脉冲激光器和两个灵敏的CCD相机组成，用于解析复杂几何形状中的流动，以及自校准的图像相关软件。该设备的收购将对拉斐特学院的研究产生重大影响，使其能够详细检查复杂几何形状的过渡流动：病变血管的血流动力学。使用PIV系统获得的数据将为正在进行的计算流体动力学（CFD）研究提供详细的速度数据，从而可以计算流体机械力。该系统还可用于鱼类游泳的跨学科研究。在数学、计算机科学和机械工程系的共同努力下，翻车鱼运动的计算研究正在进行中。拟议的设备将允许研究人员获得详细的实验数据，以验证他们的数值分析。该设备将大大扩大拉斐特学院学生接触实验技术和仪器的机会，从而有助于拉斐特学院本科生的卓越研究培训。接触和体验最先进的成像和测量技术将对拉斐特学生的教育和研究培训产生巨大的好处，他们中的许多人将继续攻读研究生院。PI在让不同背景的本科生参与有意义的研究方面有着悠久的历史。在拉斐特大学的土木、机械和电气工程系，每年招收约130名学生的7门课程将使用拟议的设备。该系统将是利哈伊谷地区本科院校中唯一的同类设备。拟议的设备将大大增强现有设施的能力，并将使上述研究目标得以实现。它还将进一步推动PI和拉斐特学院为本科生提供大量和有意义的研究机会的目标。

Proposal No. CTS-0618923Principal Investigator: Jennifer S. Rossman, Lafayette CollegeMRI: Acquisition of PIV System for Study of Biological Flows This Major Research Instrumentation grant is to acquire a Particle Image Velocimetry system to perform experiments which complement the PI's ongoing numerical analyses of the flow in blood vessels affected by aneurysm and atherosclerosis. The PIV system consists of one Nd:YAG pulsed laser and two sensitive CCD cameras to resolve flow within complex geometries, as well as self-calibrated image correlation software. The acquisition of the proposed equipment will have a significant impact on research at Lafayette College, enabling detailed examination of transitional flows in complex geometries: hemodynamics in diseased vessels. Data obtained using the PIV system will supplement ongoing computational fluid dynamics (CFD) studies with detailed velocity data so that fluid mechanical forces may be calculated. The system will also be useful to an interdisciplinary study of fish swimming. In a collaborative effort involving the mathematics, computer science, and mechanical engineering departments, computational studies of sunfish locomotion are underway. The proposed equipment will allow researchers to obtain detailed experimental data to validate their numerical analyses. This equipment will significantly expand Lafayette College students' exposure to experimental techniques and instrumentation, and thus will contribute to the exceptional research training of Lafayette College undergraduates. Exposure to, and experience with, state-of-the-art imaging and measurement techniques will be of enormous benefit to the education and research training of Lafayette students, many of whom proceed to graduate school. The PI has a strong history of involving undergraduates of diverse backgrounds in meaningful research. Up to seven courses, enrolling approximately 130 students per year, in the civil, mechanical, and electrical engineering departments at Lafayette will make use of the proposed equipment. This system will be the only equipment of its kind at an undergraduate institution in the Lehigh Valley region. The proposed equipment will dramatically augment the capabilities of existing facilities, and will allow the above research goals to be achieved. It will also further the PI's and Lafayette College's goal of providing substantial and meaningful research opportunities for undergraduate students.
