Daniel Joseph Abstract A high-speed, digital video system and image processing equipment will be used to support engineering research in two-phase-fluid flows, including: the measurement of hold-up ratios and eccentricities in water-lubricated flows of viscous materials (crude oil, slurries, and capsules); the determination of an empirical correlation between particle size and sedimentation velocity in oil-in-water emulsions (which are also used for transporting viscous materials); the study of the microstructural properties of long particles in fluidized suspensions and shear flows; the investigation of blockage effects of finite-size spheres in a monodisperse fluidized bed; and the study of interaction of a thin liquid film on a flat surface subjected to an air shear flow. ***

丹尼尔约瑟夫摘要 高速数字视频系统和图像处理设备将用于支持两相流体流动的工程研究，包括：粘性材料在水润滑流动中的滞留比和偏心率的测量（原油、泥浆和胶囊）;水包油乳状液中颗粒尺寸和沉降速度之间经验关系的确定（也用于输送粘性材料）;长颗粒在流化悬浮液和剪切流中的微观结构特性的研究;有限尺寸球体在单分散流化床中的阻塞效应的研究;以及薄液膜在受到空气剪切流的平坦表面上的相互作用的研究。 ***
