9500160 Glauser This award provides funds to permit Dr. Mark N. Glauser, Department of Mechanical and Aeronautical Engineering, Clarkson University, to pursue with Dr. Hyung Jin Sung, Department of Mechanical Engineering, Korea Advanced Institute of Science and Technology, for 24 months, a program of cooperative research on control of separated turbulent flows. The turbulent flow of a fluid over a bluff body (block) will be studied. For this flow, the collaborators will (1) study the influence of control on the spatial structure of the Proper Orthogonal decomposition (POD) eigenfunctions and (2) assess whether a POD based low dimensional dynamical systems model is feasible in this flow. Fundamental separated flows are encountered in many practical fluid engineering situations such as ducts and heat exchangers. The separated, reattached, and recirculating flow downstream of the separation point greatly enhance the amount of heat, mass, and momentum that are transferred, when compared to flows without separation at similar Reynolds number. Thus, this research is of practical as well as theoretical interest. The collaborators have extensive experience with separated flows and the application of the POD to various flows. Their strengths complement one another so that their cooperative effort should be truly beneficial in furthering understanding of the control of separated flows. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation in the project is supported by the Korea Science and Engineering Foundation (KOSEF). ***

9500160 Glauser此奖项提供资金，以允许克拉克森大学机械与航空工程系Mark N.Glauser博士与韩国先进科学技术研究院机械工程系Hyung jin Sung博士进行为期24个月的分离湍流控制合作研究计划。本课程将研究流体在钝体(块)上的湍流流动。对于这种流动，合作者将(1)研究控制对固有正交分解(POD)特征函数空间结构的影响，以及(2)评估基于POD的低维动力系统模型在这种流动中是否可行。基本分离流动在许多实际流体工程环境中都会遇到，例如管道和热交换器。与雷诺数相近的无分离流动相比，分离点下游的分离、再附着和再循环流动极大地增强了所传递的热量、质量和动量。因此，本研究既具有理论意义，又具有实践意义。合作者在分离流动和将POD应用于各种流动方面拥有丰富的经验。它们的优势是相辅相成的，因此它们的合作努力应该真正有益于进一步了解对分离流动的控制。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国参与该项目得到了韩国科学与工程基金会(KOSEF)的支持。***
