MRI: Acquisition of a Particle Image Velocimetry (PIV) system to promote state-of-the-art experimental techniques for fluid dynamics research and education at UPRM

1039915取消虽然粒子图像测速（PIV）技术是一种在研究和工业中广泛使用的流动表征方法，但波多黎各大学马亚圭斯分校（UPRM）缺乏用于研究和教育的这项技术。该提案要求获得资金，以获得3D立体PIV系统，该系统具有执行阴影大小，微型PIV和激光诱导荧光（LIF）的附加功能，以支持upm在航空航天，风力工程，水力学，生物医学，环境和地球科学，微流体和核安全方面的研究和教育工作。该设备使用一个双头激光器来照亮流场的一个切片，以及2个CCD相机，结合专门的图像采集软件和后处理功能，以确定流体中的3D速度场。该设备的特性将进一步推进与气泡和Janus颗粒动力学、近岸流体动力学、城市地区污染扩散、风与土木结构的相互作用、细菌种群行为和微流体装置中的全细胞操作相关的UPRM研究计划。本提案中要求的多功能PIV系统将加强PI、联合PI和高级人员的研究工作，这些人员都来自代表性不足的群体，在培养高质量双语西班牙裔专业人员的良好记录中服务。

1039915CancelosAlthough the Particle Image Velocimetry (PIV) technique is a method of flow characterization of wide spread use in research and industry, the University of Puerto Rico - Mayaguez (UPRM) lacks availability of this technology for research and education. This proposal requests funds to acquire a 3D stereoscopic PIV system with added capabilities to perform shadow-sizing, micro-PIV and Laser Induced Fluorescence (LIF) to support research and education efforts in aerospace, wind engineering, hydraulics, biomedical, environmental and earth sciences, microfluidics and nuclear safety at UPRM. The equipment uses a dual head laser to illuminate a slice of a flow field, and 2 CCD cameras coupled to specialized software for image acquisition with post-processing capabilities to determine 3D velocity fields in fluids. The characteristics of this equipment will further ongoing UPRM research initiatives related to bubble and Janus particles dynamics, nearshore hydrodynamics, pollution dispersion within urban areas, wind interaction with civil structures, behavior of bacteria populations and whole-cell manipulation in microfluidic devices. The versatile PIV system requested in this proposal will strengthen research efforts conducted by the PI, Co-PIs and Senior Personnel, all faculties from underrepresented groups serving in an Institution with a proven track record of producing high-quality bilingual Hispanic professionals.
