Engineering Research Equipment: Rotating Drum Camera and Particle Field Holographic System

摘要CTS-9622235 A高速转鼓相机及其组件将用于建立粒子场全息系统，用于支持多相流研究。该设备将用于在两个独立的研究项目中生成分析数据：粘弹性液体和牛顿液体在马赫数为6的激波管中的高速破碎，以及湍流颗粒流动的动态行为。分解项目的目标是产生第一个系统数据和第一个关于粘弹性液体在超音速流动中如何分解的理解。鼓相机将提供有关管理分手事件的机制的数据，基本上在不到500秒(秒)的时间内完成。粒子场全息系统将提供碎片在初始破裂后的大小、形状和分布的三维数据。颗粒流项目的目标是了解携带颗粒或纤维的湍流的动力学行为。滚筒相机将提供高分辨率、高重复率的流动事件序列。全息系统将产生关于纤维取向和絮凝的三维信息。***

ABSTRACT CTS-9622235 A high-speed rotating drum camera and the components to build a particle field holography system which will be purchased to supporting research in multiphase flows. The equipment will be used to generate a analyze data in two independent research programs: the high-speed breakup of viscoelastic and Newtonian liquids in a mach 6 shock tube, and the dynamic behavior of turbulent particle-laden flows. The objective of the breakup project is to generate the first systematic data and the first understanding of how viscoelastic liquids breakup when exposed to supersonic flows. The drum camera will provide data on the mechanisms governing the breakup event, which is essentially complete in less than 500 ( sec. The particle field holography system will provide three-dimensional data on the size, shape, and distribution of the fragments after initial breakup. The objective of the particle-laden flow project is to understand the dynamical behavior of turbulent flows that are laden with particles or fibers. The drum camera will provide high resolution, high repetition rate sequences of flow events. The holography system will yield three-dimensional information on fiber orientation and flocculation. ***
