RUI/MRI: Acquisition of a Particle Image Velocimetry System

粒子图像测速（PIV）系统需要进一步进行非定常流动和输运、沉积过程和复杂界面的资助项目。这些研究的目的是了解混合、命运、运输和沉积的基本机制。这不仅从基础研究的角度来看很重要，而且对于开发实际应用的预测工具（例如环境过程）也很重要。PIV系统能够实时跟踪两种相（颗粒或被动示踪剂和流体），使用非侵入式光学方法生成2D或3D映射。数据分析和过程量化可以很容易地使用MATLAB软件链接到仪器仪表软件。这个特性使得界面对本科生来说使用起来很友好。此外，PIV系统还能够根据驱动频率跟踪外部驱动流体中粒子的运动。有了这个独特的特性，将有可能实时研究粒子的混沌平流。该仪器将为多相流的实验和理论研究提供一个独特的机会。此外，作为一所历史上的黑人大学，泽维尔大学以其在物理学和物理科学领域的优秀非裔美国人毕业生在全国排名第一而自豪，更多的学生将直接参与一个非常重要领域的研究，并将有机会使用最先进的设备，这将更好地为他们的研究生院和研究生涯做好准备。该设备还将对教育产生直接影响，因为它将用于实验室课程，研究结果将用于高级课程的课程材料。此外，在未来，该系统还可以扩大多相流技术相关领域的教师所接受的研究范围。新奥尔良地区的其他研究人员和合作者也将从这个系统中受益。

The Particle Image Velocimetry (PIV) system is needed to further ongoing funded projects on dynamics and transport in unsteady flows, sedimentation processes, and complex interfaces. The aim of these studies is to understand the fundamental mechanisms of mixing, fate, transport, and sedimentation. This is of importance not only from the viewpoint of basic research but also to develop predictive tools (for example, for environmental processes) for practical applications.The PIV system is capable of tracking both phases (particles or passive tracers and fluid) in real time by the use of non-intrusive optical methods to generate 2D or 3D mappings. Data analysis and quantification of the processes can be easily performed using MATLAB software linked to the instrumentation software. This feature makes the interface use friendly for undergraduate students. Furthermore, the PIV system will also be able to track the motion of particles in externally driven fluids as function of the driving frequencies. With this unique feature it will be possible to investigate chaotic advection of particles in real time.The instrumentation will provide a unique opportunity to advance the ongoing research of multiphase flow at both the experimental and theoretical levels. In addition, as Xavier University, an historically black university, prides itself of being the number one producer in the nation of excellent African-American graduates in physics and physical sciences, more students will be directly involved in research in a very important area and will have the opportunity of using state-of-the art equipment, that will better prepare them for graduate school and research careers.This equipment will also have a direct educational impact as it will be used in connectionwith laboratory classes and research results will be used in curricula materials in upper level courses. Furthermore, in the future this system can also expand the horizon of the research embraced by faculty in areas of technological relevance for multiphase flows. Other researchers and collaborators in the New Orleans area will benefit from this system as well.
