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

材料研究仪器项目的这一奖项将允许匹兹堡大学购买一种视频成像系统，使主要研究人员能够在2D流动肥皂片中跟踪单个粒子的运动和染料的扩散。该视频系统由一个高速(1000fps)摄像机和一个5瓦的固态激光器组成。后者用作照亮颗粒和激发染料的强光源。该系统具有通用性，将为研究生和本科生提供流体力学和最先进的测量技术方面的培训。利用拓扑学来研究二维湍流的想法是全新的，前景看好的结果才刚刚开始出现。所要求的视频系统将进一步加深我们对湍流现象的基本了解，这些现象对于广泛的实际问题是重要的，例如天气模式、生物制剂在空气和水中的扩散、化学反应和晶体生长。材料研究仪器项目的这一奖项将允许匹兹堡大学购买一种视频成像系统，使主要研究人员能够在2D流动肥皂片中跟踪单个粒子的运动和染料的扩散。视频系统由一个高速摄像机和一个5瓦的固体激光器组成。后者用作照亮颗粒和激发染料的强光源。该系统具有通用性，将为研究生和本科生提供流体力学和最先进的测量技术方面的培训。利用拓扑学来研究二维湍流的想法是全新的，前景看好的结果才刚刚开始出现。所要求的视频系统将加深我们对湍流现象的基本了解，这些现象对于广泛的实际问题非常重要，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.
