9415709 Swinney This Americas Program award will fund a collaborative research project between dr. Harry Swinney, University of Texas, Austin, and Dr. Francisco Melo, Universidad de Santiago de Chile, on the physics of granular flow. The researchers will conduct experiments on the formation of two- dimensional spatial patterns in vertically oscillated granular materials. The formation and evolution of the patterns will be studied using digital imaging techniques and analyses will examine the effects of energy dissipation, air pressure, particle size, and forcing on the collective motion . The goal of the research is to develop new insights towards a full understanding of the underlying mechanism in the formation of the spatial patterns in these granular materials. Granular materials play an important role in industries such as mining , agriculture, and construction, yet an understanding of the fundamental processes governing the collective behavior of these materials is lacking. The proposed collaborative research should make a fundamental contribution to the understanding of the physics of granular flow, and should help in understanding the role of parameters that are varied in industrial processes involving the granular flow., ***

9415709 Swinney 该美洲计划奖将资助德克萨斯大学奥斯汀分校的Harry Swinney博士和智利圣地亚哥大学的弗朗西斯科梅洛博士关于颗粒流物理学的合作研究项目。 研究人员将对垂直振荡的颗粒状材料中二维空间图案的形成进行实验。 将使用数字成像技术研究图案的形成和演变，并分析能量耗散、气压、颗粒大小和强迫对集体运动的影响。 该研究的目标是开发新的见解，以充分理解这些颗粒材料中空间模式形成的潜在机制。 颗粒材料在采矿、农业和建筑等行业中发挥着重要作用，但人们对这些材料集体行为的基本过程缺乏了解。 拟议的合作研究应该对理解颗粒流的物理学做出根本性的贡献，并应有助于理解在涉及颗粒流的工业过程中各种参数的作用。 ***
