Unsteady Aerodynamics, Aeroacoustics and Aeroelasticity of Turbomachines
Over the past 30 years, leading experts in turbomachinery unsteady aerodynamics, aeroa- coustics, and aeroelasticity from around the world have gathered to present and discuss recent advancements in the field. The first International Symposium on Unsteady Aerodynamics, Aeroacoustics, and Aeroelasticity of Turbomachines (ISUAAAT) was held in Paris, France in 1976. Since then, the symposium has been held in Lausanne, Switzerland (1980), Cambridge, England (1984), Aachen, Germany (1987), Beijing, China (1989), Notre Dame, Indiana (1991), Fukuoka, Japan (1994), Stockholm, Sweden (1997), and Lyon, France (2000). The Tenth ISUAAAT was held September 7-11, 2003 at Duke University in Durham, North Carolina. This volume contains an archival record of the papers presented at that meeting.
The ISUAAAT, held roughly every three years, is the premier meeting of specialists in turbomachinery aeroelasticity and unsteady aerodynamics. The Tenth ISUAAAT, like its predecessors, provided a forum for the presentation of leading-edge work in turbomachinery aeromechanics and aeroacoustics of turbomachinery. Not surprisingly, with the continued development of both computer algorithms and computer hardware, the meeting featured a number of papers detailing computational methods for predicting unsteady flows and the resulting aerodynamics loads. In addition, a number of papers describing interesting and very useful experimental studies were presented. In all, 44 papers from the meeting are published in this volume.
The Tenth ISUAAAT would not have been possible without the generous financial support of a number of organizations including GE Aircraft Engines, Rolls-Royce, Pratt and Whitney, Siemens-Westinghouse, Honeywell, the U. S. Air Forces Research Laboratory, the Lord Foundation of North Carolina, and the Pratt School of Engineering at Duke University. The organizers offer their sincere thanks for the financial support provided by these institutions. We would also like to thank the International Scientific Committee of the ISUAAAT for selecting Duke University to host the symposium, and for their assistance in its organization. Finally, the organizers thank Loraine Ashley of the Department of Mechanical Engineering and Materials Science for her Herculean efforts organizing the logistics, communications, and finances required to host the conference.
The Eleventh ISUAAAT will be held in Moscow, Russia, September 4-8, 2006, and will be hosted by the Central Institute of Aviation Motors. Dr. Viktor Saren, the hosting member of the International Scientific Committee, will serve as deputy chair of the symposium; Dr. Vladimir Skibin, the General Director of CIAM, will serve as chair.
