This proposal aims to acquire a High-Speed Volumetric Particle Tracking Velocimetric (VTPV) system capable of tracking the three-dimensional position of multiple particles within a measurement fluid volume, and subsequent calculation of velocity, or acceleration of the particles. Active research projects that would benefit from the instrument range from blood pumps to miniature medical devices to microplastics transport in the environment. The list of active research projects is expected to grow with new opportunities and collaborations. The proposed system will improve Rochester Institute of Technology’s ability to conduct leading-edge research by enhancing the infrastructure for research and education. Specifically, planned research and training at Rochester Institute of Technology and the region includes (1) student training and research, (2) two new multidisciplinary courses, and (3) training workshops. The proposed VTPV instrument is comprised of high intensity laser illumination, a set of digital cameras, and specialized optics that are integrated with dedicated synchronization hardware and image processing software. Each of the five projects described has previously benefitted from acquisition of two-dimensional fluid or particle data with the existing outdated 2D measurement system. The new data to be acquired by the proposed three-dimensional high-speed system will increase quantitative understanding of underlying flow physics, and in some cases, providing the first ever quantitative data relevant for the application.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.

该提议旨在获得高速体积粒子跟踪测速（VTPV）系统，该系统能够跟踪测量流体体积内的多个粒子的三维位置，并且随后计算粒子的速度或加速度。将受益于该仪器的积极研究项目范围从血泵到微型医疗设备到环境中的微塑料运输。活跃的研究项目名单预计将随着新的机会和合作而增长。拟议的系统将提高罗切斯特理工学院的能力，通过加强研究和教育的基础设施进行前沿研究。具体而言，计划在罗切斯特理工学院和该地区的研究和培训包括（1）学生培训和研究，（2）两个新的多学科课程，（3）培训讲习班。拟议的VTPV仪器是由高强度激光照明，一组数码相机，和专用的光学集成与专用的同步硬件和图像处理软件。所描述的五个项目中的每一个都曾受益于使用现有过时的2D测量系统采集二维流体或颗粒数据。新的数据将获得拟议的三维高速系统将增加定量的了解基本的流动物理，并在某些情况下，提供有史以来第一次定量的数据相关的应用程序。这一奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。
