MRI: Acquisition of a Tomographic Particle Image Velocimetry System

克拉克森大学将获得主要研究仪器奖，获得层析粒子图像测速系统。该仪器的获得将促进科学研究在各种主题上的进步，例如人类声音的产生，水文中沉积物和碎片运输的建模和预测以及对生物多样性和生态的影响，以及碳封存的新方法。确保克拉克森大学整个校园广泛和公平地进入系统，将克拉克森置于流体动力学研究能力的最前沿，并鼓励和促进新的跨学科研究努力。该仪器的可用性将通过实验技术的课堂教学以及关于该系统实际使用的动手实验室培训，为本科生和研究生提供教育机会。克拉克森大学为大量在STEM领域代表性不足的学生提供服务，这些学生来自较低的社会经济背景。接触和使用这种最先进的测量系统将激励下一代科学家和工程师。层析粒子图像测速系统的主要优点是能够同时解析体积内所有三个坐标方向上的速度矢量和速度梯度张量。这种能力将显著推进克拉克森大学在以下特定领域的研究工作：(1)航空声学声源识别和浊音产生中的流体-结构相互作用，以确定病理行为如何影响语音功能；(2)量化由冰和碎屑障碍物引起的河流的水流形态，并应用于减轻洪水事件造成的损害；(3)通过量化与物理、生物和生态相关的泥沙运输过程，增强城市河流的生态功能。(4)控制翼型动态失速以提高飞机性能；(5)量化地质裂缝多相流以优化碳固存；(6)最小化接缝流阻力，用于提高大型车辆运输的燃油效率；(7)开发一种从实验速度场估计压力场的新技术。预计实施一项战略，即仪器可用性的百分比专门用于新用户，免费，将催化更多新的和令人兴奋的跨校园跨学科研究工作。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

With the Major Research Instrumentation award, Clarkson University will acquire a tomographic particle image velocimetry system. Acquisition of the instrument will facilitate advancements in scientific research across a diverse range of topics, such as human voice production, modeling and prediction of sediment and debris transport in hydrology and the impact on biodiversity and ecology, and novel approaches for carbon sequestration. Ensuring broad and equitable access to the system across the entire campus of Clarkson University will place Clarkson at the forefront of fluid dynamics research capabilities and encourage and promote novel cross-disciplinary research endeavors. Availability of this instrument will afford educational opportunities at both the undergraduate and graduate levels through classroom instruction on the experimental technique, as well as hands-on laboratory training on the practical use of the system. Clarkson University serves a significant number of students that are underrepresented in STEM fields and that come from lower socioeconomic backgrounds. Exposure to, and utilization of, this state-of-the-art measurement system will inspire the next generation of scientists and engineers. The primary advantage of a tomographic particle image velocimetry system is the ability to simultaneously resolve both the velocity vector and the velocity gradient tensor over all three coordinate directions within a volume. This capability will significantly advance research efforts at Clarkson University in the following specific areas: (1) aero-acoustic sound source identification and fluid-structure interactions in voiced speech production to identify how pathological behaviors impact vocal function, (2) quantification of flow morphologies in rivers arising from ice and debris obstructions with application to mitigating damage arising from flooding events, (3) enhancing ecological function in urban streams through quantification of the physical, biological, and ecologically-relevant sediment transport processes, (4) control of dynamic stall on airfoils to enhance aircraft performance, (5) quantification of multiphase flows through geological fractures to optimize carbon sequestration, (6) drag minimization of juncture flows with application to increasing fuel efficiency in large vehicle transport, and (7) development of a novel technique for estimating pressure fields from experimental velocity fields. It is anticipated that implementing a strategy whereby a percentage of the instrument availability is dedicated to new users, at no cost, will catalyze additional new and exciting cross-disciplinary research efforts across campus.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.
