0959915Wootton"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."An endoscopic particle image velocimetry (PIV) system and multiprocessor computer will be acquired for mechanical and biomedical engineering fluid mechanics research and projects at the Cooper Union. The PIV system is designed for visualizing and measuring two-dimensional velocity and turbulence fields in steady and unsteady flows of gas or liquid, at sample rates up to 15 fields per second, in internal flow devices with restricted optical access. Conventional light sheet optics will be acquired for use in wind tunnels and other optically accessible experiments. The multiprocessor computer is a custom 16-core workstation with 64 GB of RAM, designed for large computational fluid dynamics model simulations. These powerful tools will be used to train masters and undergraduate students in fluid mechanics research using both experimental and computational methods, in a variety of projects, including fluid mechanics of rigid and deformable models of the upper airway in obstructive sleep apnea, fluid mechanics of chronic cyclic hypoxia research equipment, improved in-cylinder flow characteristics in homogeneous charge compression ignition engines to reduce hydrocarbon emissions, and a variety of undergraduate automotive and wind tunnel projects. Undergraduate students will be exposed to PIV in required fluid mechanics and lab courses, and will be able to receive training and apply PIV to research and design projects. Students taking computational fluid dynamics courses will be introduced to parallel processing and have the opportunity to use the multiprocessor workstation during course projects as well as research projects.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“将为库珀联盟的机械和生物医学工程流体力学研究和项目购买内窥镜粒子图像测速（PIV）系统和多处理器计算机。PIV系统设计用于可视化和测量气体或液体的稳定和非稳定流中的二维速度和湍流场，采样速率高达每秒15个场，在具有受限光学访问的内部流设备中。传统的光片光学将用于风洞和其他光学实验。多处理器计算机是一个定制的16核工作站，具有64 GB RAM，专为大型计算流体动力学模型模拟而设计。这些强大的工具将被用来培养硕士和本科生在流体力学研究中使用实验和计算方法，在各种项目，包括流体力学的刚性和变形模型的上气道阻塞性睡眠呼吸暂停，流体力学的慢性循环缺氧研究设备，改善缸内流动特性在均质充量压缩点火发动机，以减少碳氢化合物排放，以及各种本科汽车和风洞项目。本科生将在所需的流体力学和实验室课程中接触PIV，并将能够接受培训并将PIV应用于研究和设计项目。参加计算流体动力学课程的学生将被引入并行处理，并有机会在课程项目和研究项目期间使用多处理器工作站。
