讲座人 Earl H. Dowell
讲座人介绍 Dr. Dowell is an elected member of the National Academy of Engineering, an Honorary Fellow of the American Institute of Aeronautics and Astronautics (AIAA) and a Fellow of the American Academy of Mechanics and the American Society of Mechanical Engineers.  He has also served as Vice President for Publications and member of the Executive Committee of the Board of Directors of the AIAA; as a member of the United States Air Force Scientific Advisory Board; the Air Force Studies Board, the Aerospace Science and Engineering Board and the Board on Army Science and Technology of the National Academies; the AGARD (NATO) advisory panel for aerospace engineering, as President of the American Academy of Mechanics, as Chair of the US National Committee on Theoretical and Applied Mechanics and as Chairman of the National Council of Deans of Engineering.  From the AIAA he has received the Structure, Structural Dynamics and Materials Award, the Von Karman Lectureship the Crichlow Trust Prize and the Reed Aeronautics Award; from the ASME he has received the Spirit of St. Louis Medal, the Den Hartog Award and Lyapunov Medal; and he has also received the Guggenheim Medal which is awarded jointly by the AIAA, ASME, AHS and SAE.
 He has served on the boards of visitors of several universities and is a consultant to government, industry and universities in science and technology policy and engineering education as well as on the topics of his research.
 Dr. Dowell research ranges over the topics of aeroelasticity, nonsteady aerodynamics, nonlinear dynamics and structures. In addition to being author of over three hundred research articles, Dr. Dowell is the author or co-author of four books, "Aeroelasticity of Plates and Shells", "A Modern Course in Aeroelasticity", "Studies in Nonlinear Aeroelasticity" and “Dynamics of Very High Dimensional Systems”.  His teaching spans the disciplines of acoustics, aerodynamics, dynamics and structures.
 Dr. Dowell received his B.S. degree from the University of Illinois and his S.M. and Sc.D. degrees from the Massachusetts Institute of Technology.  Before coming to Duke as Dean of the School of Engineering, serving from 1983-1999, he taught at M.I.T. and Princeton.  He has also worked with the Boeing Company.
 
中文介绍:
Earl H. Dowell (厄尔 休 道尔)是美国杜克大学William Holland Hall教授,美国工程院院士,美国航空航天个人最高荣誉奖AIAA Reed Aeronautics Award获得者。此外他还获得了Guggenheim Medal, Lyapunov Award, Walter J. And Angelina J. Crichlow Trust Prize和Theodore Van Karman Lectureship等十余项重量级学术奖励。Earl H. Dowell还担任了American Institute of Aeronautics and Astronautics (AIAA) Honor fellow(荣誉理事), American Academy of Mechanics (AAM) fellow和American Society of Mechanical Engineers (ASME) fellow等学术职务。
Earl H. Dowell在气动弹性、结构动力学和非定常空气动力学研究方向取得先驱性贡献,所完成的研究工作对推动航空航天领域技术发展产生了巨大的影响。标志性研究结果有:
1)揭示壁板颤振的非线性本质特征对解决飞行器壁板破坏问题起到了决定性贡献。
2)首位将几何非线性引入到旋翼气动弹性问题研究中,给出的非线性梁结构基本方程被应用于无铰链旋翼悬停、前飞实验研究,促进了直升机旋翼性能的大幅提高。
3)大力推进Reduced Order Modeling (ROM)建模理论方法研究,极大的提升了计算结构动力学、计算流体力学问题研究的计算能效。
目前,Earl H. Dowell发表近350篇学术论文,近5年的年平均引用次为1250+,i10指数为273。在其发表的论文中,“Modeling of Fluid-Structure Interaction”是Annual review of Fluid Mechanics期刊(SCI分区,力学排名第一、物理学Top期刊,IF为12.+)中,流固耦合问题引用次数最多的文献。《A Modern Course in Aeroelasticity》(40多年不断更新、目前为第5版)被誉为气动弹性领域内的先锋性著作。
讲座内容 Aeroelastic oscillations may be used to convert mechanical energy into electrical energy using the wind as the primary energy course.
非线性系统动力学与压电材料电子技术的结合
Lessons learned and current challenges for engineering education in the United States are discussed.
这个题目是关于工科大学教育的未来,Dowell教授担任过美国大学工学联盟的主席,此题目他在美国很多大学都讲过,作为美国顶尖的工学教育者,相信他会有自己的视角的.
