Workshop on Multiphase Continuum Modeling of Particulate Flows, December 9-11, 2015, Gainesville, FL

这个奖项将使代表不同学科的美国科学家和工程师参加一个名为“颗粒流动的多相连续体建模”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。研讨会将探索改进连续体模型的发展，以准确预测颗粒流动的动力学。虽然控制简单流体流动的运动方程已经很好地建立了，但相应的颗粒流动方程提出了特殊的挑战。为了准确地计算悬架的流动，必须对流动引起的悬架微观结构重排进行适当的建模。研讨会将探讨实验结果和模拟结果，试图调和由连续体模型描述的流动数据和信息。参与者将被要求确定各种颗粒流动制度共同面临的主要突出挑战。确定共同的问题将有助于减少跨学科的重复工作，并将社区集中在以统一的方式解决颗粒物流动问题的集中步骤上。微粒流在自然和工业过程中无处不在。河流和海洋沉积物的运动、复合材料制造过程中纤维的流动、动脉和静脉中的血液流动、生物反应器中气泡的运动、新材料定向组装过程中胶体颗粒的流动等等，这只是其中的几个例子。尽管它们的外观很普通，但这些流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。该奖项将帮助支持科学家和工程师，特别是年轻的研究人员参加本次研讨会。

#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.
