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. ***

小行星9314799 这个美洲计划奖将支持约翰·S。明尼苏达大学圣保罗分校的Dahler博士与Hector I博士合作进行了一项研究。智利天主教大学的Jorquera。 这项研究的目的是测试，修改和扩展一个新的理论，由两位研究人员开发的稠密胶体悬浮液的流动特性。 将根据这一理论进行数值计算。 该理论将被用来预测其他流体性质，如悬浮液的粘弹性响应随时间变化的流动，扩散和沉降的胶体颗粒和散射光和热中子的光谱的速率。 由于理论研究的技术复杂性和微妙性，这一领域的进展一直很缓慢。 因此，增加对这些材料的传输特性的了解将在许多工业领域产生巨大的技术影响，从生物技术到油漆和混凝土的混合和应用。 研究人员的分析和数字专门知识的互补性可能会导致该领域的进展。 ***
