ABSTRACT CTS-9402682 I. Manas-Zloczower An experimental and theoretical study on the structure, breakage and dispersion of clusters of particulate materials by hydrodynamics stresses will be undertaken. Three materials with similar macroscopic behavior in dispersion, carbon black, titanium dioxide, and silica clusters, will be considered for experiments. The physical and chemical characteristics of solids and carrier fluid, interfacial properties of individual units comprising the clusters, and overall properties of the clusters assemblies and their cohesivity will be investigated, including the effect on the fluid infiltration into the agglomerates, inter-aggregate bonds and breakage, cohesivity, dispersion processes, fluid flow rates of deformation. The dispersion of small particle aggregates is important in many industrial processes in chemical, minerals and food industries. If successful, the project will improve understanding for the design of mixing liquid-solids systems.

摘要CTS-9402682 I.马纳斯-兹洛措沃 本文将对流体力学应力作用下颗粒材料团簇的结构、破碎和分散进行实验和理论研究。 三种材料具有相似的宏观行为的分散，炭黑，二氧化钛，和二氧化硅簇，将被认为是实验。 固体和载体流体的物理和化学特性，包括集群的各个单元的界面特性，和集群组件的整体性能和它们的凝聚力将被调查，包括对流体渗透到团聚体，聚集体间的键合和断裂，凝聚力，分散过程，变形的流体流速的影响。 小颗粒聚集体的分散在化学、矿物和食品工业的许多工业过程中是重要的。 如果成功，该项目将提高对混合液固系统设计的理解。
