Proposal Number: CTS 9977605Principal Investigator: R. SmithThis Major Research Instrumentation (MRI) award supports the acquisition of a Particle Image Velocimetry (PIV) and a spectrometer for use in MOCVD reactors. The PIV will be used to in the design of flow in microchannels and reaction chambers. The micron resolution measurements of the PIV system will be combined with the nano-resolution of an Atomic Force Microscope to study microscale transport associated with complicated surfaces. The PIV will also the measurement of velocity fields immediately above the surface with simultaneous AFM measurements will allow the examination of the evolution of the surface. The instruments will be used of study mixing and transport processes associated with biological fluid mechanics, such as tissue engineering and endothelial tissue evolution.Spatial mixing issues in MOCVD reactors will also be investigated. The use of the spectrometer and CCD arrays will give estimates of multiple gas concentrations at multiple points within the reactor. Fiber optic lines will be used to pipe the light from various points within the reaction chamber. This will give the capability of developing and experimentally verifying models of gas flow and mixing dynamics. These models will be used to design high performance feedback controllers.hot wire anemometry and data acquisition system to support the Multidisciplinary Undergraduate Research in Turbulence project at Valparaiso University. The project will investigate atmospheric and engineering scale turbulent transport. The project's main focus is on the education and training of students in both Colleges of Engineering and of Arts and Sciences in the specific areas of atmospheric turbulence, environmental pollution in turbulent air and water flows, and generalized modeling of the turbulent transport of mass and thermal energy. In addition, it will be used in developing an educational seminar for faculty from nearby institutions.

提案编号：CTS 9977605原理研究者：R。Smiththis Thinthis主要研究仪器（MRI）奖支持粒子图像速度法（PIV）和用于MOCVD反应器中的光谱仪。 PIV将用于微通道和反应室的流动设计。 PIV系统的微分辨率测量将与原子力显微镜的纳米分辨率相结合，以研究与复杂表面相关的显微镜转运。 PIV还将通过同时进行AFM测量值的速度场测量速度场，将允许检查表面的演化。这些仪器将用于研究与生物流体力学相关的研究混合和运输过程，例如组织工程和内皮组织进化。还将研究MOCVD反应堆中的空间混合问题。光谱仪和CCD阵列的使用将对反应器内多个点的多个气体浓度进行估计。光纤线将用于从反应室内的各个点上管道。这将赋予开发和实验验证气流和混合动力学模型的能力。这些模型将用于设计高性能反馈控制器。HAT电线动态测定法和数据采集系统，以支持Valparaiso University在湍流项目中的多学科本科研究。该项目将研究大气和工程规模的湍流运输。 该项目的主要重点是在特定的大气湍流，湍流空气和水流中的环境污染以及质量和热量的湍流运输的广义模型中，工程学院以及工程和科学学院的教育和培训都在教育和培训活力。此外，它将用于开发附近机构的教师教育研讨会。
