The widespread uses of suspensions in industry such as paint products, slurry fuels, and coal slurry transportation have for long provided motivations for their study. Recently, additional impetus for study of suspensions has been generated since coal-water slurry (CWS) fuel was recognized as the potentially most economical means for the usage of coal, one of the nation's most abundant energy resources, to replace oil in utility boilers. The research is concerned with experimental and theoretical studies of two related subjects, rheology and airblast atomization, in concentrated suspensions of particles larger than colloidal sizes. The major research objective is to improve understanding of the structure and the underlying mechanisms of concentrated suspensions with application to CWS technology. Research emphasis will be placed on particle-particle and particle-fluid interactions as affected by particle surface property.

悬浮液在工业中的广泛应用，如涂料产品、浆料燃料和煤浆运输，长期以来为它们的研究提供了动力。最近，额外的动力悬浮液的研究已经产生，因为水煤浆（CWS）燃料被认为是潜在的最经济的手段使用的煤，国家最丰富的能源资源之一，以取代石油在电站锅炉。本研究涉及两个相关课题的实验和理论研究，即大于胶体尺寸的颗粒的浓缩悬浮液中的流变学和气流雾化。主要的研究目标是提高对浓悬浮体的结构和潜在机理的理解，并将其应用于水煤浆技术。研究重点将放在颗粒与颗粒和颗粒与流体的相互作用，颗粒表面性质的影响。
