Workshop on Multiphase Turbulence: Dust Storms, Erosion, Hurricanes and Tornadoes

提案编号： CBET-0732387主要制造商：D.D.约瑟芬研究所： 这笔赠款用于提供部分资金，主要用于旅费和出席“多相湍流：沙尘暴、侵蚀、飓风和龙卷风讲习班”。研讨会的目的是了解颗粒对湍流的影响，以及湍流对颗粒输送和流化的影响。这笔赠款将支持美国参加研讨会，以形成明尼苏达大学，西安交通大学国家重点实验室，北京大学新工程学院湍流研究中心和澳大利亚墨尔本大学之间的合作。这项研究的一个目标是通过系统和受控的实验室实验，了解湍流强度和颗粒大小、重量和浓度对沙尘暴、侵蚀、飓风和龙卷风问题的影响。沙尘暴是一种环境危害。胶体部分是持久的和污染的。所提出的实验，特别是对流单体中湍流的实验，显然是进行受控气溶胶研究的一种新方法。这些实验是一个项目的第一阶段，该项目旨在建立有关地球物理湍流中颗粒多相流体力学的事实。我们的第一个目标是建立粒子效应的相关性。这次研讨会的主题可以形成一个连贯和可识别的科学和环境研究主题。这将有助于就上述问题形成深入和重点突出的国际合作，所支助的讲习班是这一努力的一个方面。 NSF的资金将主要用于支持年轻研究人员参加研讨会。

PROPOSAL NO.: CBET-0732387 PRINCIPAL INVESTIGATORS: D.D. JOSEPHINSTITUTION: UNIVERSITY OF MINNESOTA TWIN CITIES "WORKSHOP ON MULTIPHASE TURBULENCE: DUST STORMS, EROSION, HURRICANES AND TORNADOES"The grant is for partial funding, primarily for the travel and attendance at the "Workshop on Multiphase Turbulence: Dust Storms, Erosion, Hurricanes and Tornadoes". The objectives of the workshop are to understand the effects of particles on the modification of turbulence and the effects of turbulence on the transport and fluidization of particles. The grant will support US participation in the workshop to form a collaboration between the University of Minnesota, the key state laboratory of X'ian Jiaotong University, the center for the study of turbulence in the new school of engineering at Peking University and the University of Melbourne, Australia. One goal of this research is to understand the effects of turbulent intensity and particle size, weight and concentration on the problems of dust storms, erosion, hurricanes and tornadoes from systematic and controlled laboratory experiments. Dust storms are an environmental hazard. The colloidal fractions are long lasting and polluting. The proposed experiments, particularly those in turbulent flow in convection cells, are apparently a new way of doing controlled aerosol studies. These experiments are a first phase in a program to establish facts about the multiphase fluid mechanics of particles in geophysical turbulent flows. Our first goal is to establish correlations for the effects of the particles. The topic of this workshop can form a coherent and identifiable topic of scientific and environmental research. This will help form a deep and focused international collaboration on the problems just described and the supported workshop is one facet of this effort. NSF funding will be used primarily to support young researchers to attend the workshop.
