Acquisition of Video Camera and 5-Watt Laser for Turbulence Research and Education

这份来自材料研究仪器项目的合同将允许匹兹堡大学购买一个视频成像系统，该系统将允许主要研究人员跟踪单个粒子的运动和染料在二维流动肥皂膜中的扩散。视频系统由一个高速（1000 fps）摄像机和一个5瓦的固态激光器组成。后者作为强光源照亮粒子和激发染料。该系统是一种通用工具，将用于培养研究生和本科生在流体动力学和最先进的测量技术。使用拓扑学来研究二维湍流的想法是全新的，有希望的结果刚刚开始出现。所要求的视频系统将进一步加深我们对湍流现象的基本理解，这些现象对许多实际问题都很重要，例如天气模式、生物制剂在空气和水中的扩散、化学反应、这份来自材料研究仪器项目的合同将允许匹兹堡大学购买一个视频成像系统，该系统将允许主要研究人员跟踪单个粒子的运动和染料在二维流动肥皂膜中的扩散。视频系统由一个高速摄像机和一个5瓦的固态激光器组成。后者作为强光源照亮粒子和激发染料。该系统是一种通用工具，将用于培养研究生和本科生在流体动力学和最先进的测量技术。使用拓扑学来研究二维湍流的想法是全新的，有希望的结果刚刚开始出现。所要求的视频系统将进一步加深我们对湍流现象的基本理解，这些现象对于广泛的实际问题非常重要，例如天气模式，空气和水中生物制剂的分散，化学反应和晶体生长。

This award from the Instrumentation for Materials Research Program will allow the University of Pittsburgh to purchase a video imaging system that will allow the principal investigators to follow individual particle motion and spreading of dyes in a 2D flowing soap film. The video system consists of a high-speed (1000 fps) video camera and a 5Watt solid-state laser. The latter serves as an intense light source for illuminating the particles and for excitation of the dye. The system is one of general utility and will serve to train graduate as well as undergraduate students in fluid dynamics and state-of-the-art measurement techniques. The idea of using topology to study 2D turbulence is entirely new and promising results just beginning to emerge. The requested video system will further our fundamental understanding of turbulence phenomena which are important for a wide range of practical problems, such as weather patterns, dispersion of biological agents in air and in water, chemical reactions, and crystal growth..This award from the Instrumentation for Materials Research program will allow the University of Pittsburgh to purchase a video imaging system that will allow the principal investigators to follow individual particle motion and spreading of dyes in a 2D flowing soap film.
