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兹分校(UPRM)缺乏这项技术用于研究和教育。该提案要求获得资金，以购买一个3D立体PIV系统，该系统具有更多执行阴影大小、微型PIV和激光诱导荧光(LIF)的能力，以支持UPRM在航空航天、风工程、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。该设备使用双头激光照射一片流场，两个CCD摄像机连接到专门的图像采集软件，并具有后处理能力，以确定流体中的三维速度场。该设备的特点将进一步推动正在进行的UPRM研究活动，这些活动涉及气泡和Janus颗粒动力学、近岸水动力学、城市地区的污染扩散、风与民用结构的相互作用、细菌种群的行为以及微流控设备中的全细胞操纵。本提案要求的多功能PIV系统将加强PI、共同PIS和高级人员开展的研究工作，这些人员都来自任职于某一机构的代表人数不足的群体，他们在培养高素质的双语拉美裔专业人员方面有良好的记录。

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.
