U.S.-Australia Cooperative Research: Numerical Simulations and Stochastic Modeling of Turbulent Mixing and Dispersion

小行星9526868 该奖项将在两年内资助格鲁吉亚理工学院航空航天工程系的杨培权博士和该系研究生凯瑟琳莫斯利与迈克尔S. Borgas来自位于维多利亚Mordialloc的英联邦科学和工业研究组织（CSIRO）大气研究部。 合作研究将集中在湍流气流中污染物传输和扩散的模拟和随机建模。 在空气污染问题中，由局部污染源产生的平均浓度区域主要由流体元素的无序运动确定，最好使用流体力学的拉格朗日方法来描述。 这些数据很难测量，可以从湍流中精确的、瞬时的动量和标度输运方程的数值模拟中提取。 这项研究是特别及时的，在加强环境中的湍流扩散的随机模型的发展。 CSIRO实验室进行了一项大型大气研究计划，与格鲁吉亚理工学院的并行计算设施相结合，将使这项研究得以实现。 在澳大利亚，通过工业、科学和旅游部提供支助。

9526868 Yeung This award will support the travel costs, over a two year period, to enable Dr. Pui-kuen Yeung of the Aerospace Engineering Department at the Georgia Institute of Technology, and for Catherine Moseley, a graduate student in the Department, to conduct collaborative research with Dr. Michael S. Borgas from the Division of Atmospheric Research of the Commonwealth Scientific and Industrial Research Organization (CSIRO) located at Mordialloc, Victoria. The cooperative research will focus on simulation and stochastic modeling of contaminant transport and dispersion in turbulent airflows. In air pollution problems the mean concentration region arising from localized pollution sources is primarily determined by a disorderly motion of fluid elements best described using the Lagrangian approach of fluid mechanics. The data, which are difficult to measure, may be extracted from numerical simulations of the exact, instantaneous momentum and scaler transport equations in turbulence. This research is of particular timeliness in enhancing the development of stochastic models of turbulent dispersion in the environment. The CSIRO laboratory conducts a large atmospheric research program, and that combined with the parallel computing facilities available at the Georgia Institute of Technology, will enable this study to be realized. Support in Australia is provided through the Department of Industry, Science and Tourism (DIST).
