U.S.-Chile: Statistical Mechanical Theory of Suspension

9314799 Dahler这个美洲项目奖将支持明尼苏达大学圣保罗分校的John S.Dahler博士与智利加托利卡大学的Hector I.Jorquera博士合作进行研究。这项研究的目的是检验、修正和推广两位研究人员提出的关于稠密胶体悬浮液流动特性的新理论。将进行基于该理论的数值计算。该理论将用于预测其他流体性质，如悬浮液对随时间变化的流动的粘弹性响应、胶体颗粒的扩散和沉积速度以及散射光和热中子的光谱。由于理论研究的技术复杂性和微妙之处，这一领域的进展缓慢。因此，越来越多地了解这些材料的运输特性将在许多工业领域产生巨大的技术影响，从生物技术延伸到涂料和混凝土的混合和应用。研究人员在分析和数值方面的专业知识的互补性很可能导致该领域的进展。***

9314799 Dahler This Americas Program award will support Dr. John S. Dahler, of the University of Minnesota, St. Paul in a research collaboration with Dr. Hector I. Jorquera, of the Pontificia Universidad Catolica de Chile. The purpose of the research is to test, modify and extend a new theory, developed by the two researchers, of the flow characteristics of dense colloidal suspensions. Numerical computations based upon this theory will be performed. The theory will be used to predict other fluid properties such as a suspension's viscoelastic response to time-dependent flows, the rates of diffusion and sedimentation of the colloidal particles and the spectra of scattered light and thermal neutrons. Because of the technical complexity and subtlety of theoretical research, progress in this field has been slow. Therefore, increasing understanding of the transport properties of these materials would have an enormous technological impact in a number of industrial fields, extending from biotechnology to mixing and application of paint and concrete. The complementarity of the researchers expertise, analytic and numerical, is likely to lead to progress in the field. ***
