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. MANAS-ZLOCZOWER将通过流体力学应力进行有关颗粒材料簇的结构，断裂和分散的实验和理论研究。 将考虑三种具有相似宏观行为的材料，黑色碳，二氧化钛和二氧化硅簇的三种材料将被考虑进行实验。 将研究固体和载体流体的物理和化学特征，包含簇的单个单元的界面特性，以及簇组件的整体特性及其凝聚力，包括对液体浸润的影响断裂，凝聚力，分散过程，变形的流体流速。 在化学，矿物质和食品工业的许多工业过程中，小粒子聚集体的分散很重要。 如果成功，该项目将提高对混合液体固体系统的设计的理解。
