Dynamics of Particles in Rotating Viscous Flows and the Centrifugation of Suspensions

摘要CTS-9422752 将采用理论和计算方法研究旋转场中的多相流。 主要目标是开发和实施的边界积分法求解线性化方程的运动在旋转粘性流在相对较低的雷诺数（O看到近似），并考虑泰勒列周围形成的单个颗粒或气泡。 多个粒子的相互作用的研究，有和没有固体边界的存在下，将提供深入了解旋转悬浮液的微观结构和流变行为的测定。 设计了一个描述两粒子泰勒柱相互作用的可视化实验。 拟议的研究与环境，矿物和生物的分离过程;燃烧和加工工业中的混合;复合材料的制造;以及地球物理流体运动有关。 ***

ABSTRACT CTS-9422752 A theoretical and computational approach will be undertaken to study multiphase flow in a rotating field. The main objective is the development and implementation of a boundary integral method for solving the linearized equation of motion in rotating viscous flow at relatively low Reynolds numbers (O seen approximation), and considering the Taylor columns formed around individual particles or bubbles. The study of multiple particle interactions, with and without the presence of solid boundaries, will provide insights into the microstructure of rotating suspensions and determination of rheological behavior. A visualization experiment to describe the Taylor column interactions of two particles is planed. The proposed study has relevance to separation process in environment, minerals and biology; mixing in combustion and processing industries; manufacturing of composite materials; and geophysical fluid motion. ***
