#1602937Butler, Jason E.This award will enable U.S. scientists and engineers representing diverse disciplines to participate in a workshop titled "Multiphase Continuum Modeling of Particulate Flows," which will be held December 9 - 11, 2015 in Gainesville, FL. The workshop will explore the development of improved continuum models to accurately predict the dynamics of particulate flows. Although the equations of motion that govern flows of simple fluids are well established, the corresponding equations for particulate flows pose special challenges. Flow-induced rearrangements of the suspension microstructure must be modeled properly in order to calculate accurately the flow of the suspension. The workshop will explore experimental results and simulation outcomes to try to reconcile data and information regarding flows describe by continuum models. Participants will be asked to identify key outstanding challenges that are common to a wide range of particulate flow regimes. The identification of common issues will help reduce duplication of efforts across disciplines and focus the community on concentrated steps toward solving particulate flow problems in a unified way. Particulate flows are ubiquitous in natural and industrial processes. The motion of river and ocean sediment, the flow of fibers in the manufacturing of composite materials, the flow of blood through arteries and veins, the motion of bubbles in biological reactors, the flow of colloidal particles in directed-assembly of novel materials are just a few examples. Despite their commonplace appearance, these flows pose unique challenges for modeling and computation. Solving these challenges could help scientists and engineers better predict the behavior of these materials in flow, design improved equipment for advanced manufacturing, and reduce costs and environmental impacts. This award will help support scientists and engineers, especially young researchers, to attend this workshop.

#1602937Butler，Jason E.该奖项将使代表不同学科的美国科学家和工程师能够参加一个名为“颗粒流的多相连续建模”的研讨会，该研讨会将于2015年12月9日至11日在佛罗里达州盖恩斯维尔举行。 虽然简单流体的运动方程已经建立得很好，但颗粒流的相应方程却提出了特殊的挑战。 为了准确地计算悬浮液的流动，必须对悬浮液微结构的流动诱导重排进行适当的建模。 研讨会将探讨实验结果和模拟结果，试图协调数据和信息的流动描述的连续模型。 与会者将被要求确定关键的突出的挑战，是共同的广泛的颗粒流制度。 共同问题的识别将有助于减少跨学科的重复工作，并使社区集中精力，以统一的方式解决颗粒流问题。 颗粒流在自然和工业过程中普遍存在。 河流和海洋沉积物的运动，复合材料制造中的纤维流动，动脉和静脉中的血液流动，生物反应器中气泡的运动，新材料直接组装中胶体颗粒的流动只是几个例子。 尽管它们的外观很普通，但这些流动对建模和计算提出了独特的挑战。 解决这些挑战可以帮助科学家和工程师更好地预测这些材料在流动中的行为，为先进制造设计改进的设备，并降低成本和环境影响。 该奖项将有助于支持科学家和工程师，特别是年轻的研究人员参加这次研讨会。
