Preface
This volume and its two companion volumes contain the papers presented at the Fifth International Conference on Turbulence and Shear Flow Phenomena (TSFP-5), held at the Technische Universität München from August 27 to 29, 2007. The series of biennial TSFP Symposia originated in Santa Barbara, California, in 1999, and subsequent meetings were held in Stockholm, Sweden (2001), Sendai, Japan (2003) and Williamsburg, Virginia (2005). The Conference may be claimed to have established themselves as the principal global forums for reporting and disseminating recent and ongoing research on turbulence and shear-flow phenomena.
The subjects of turbulence, transition, flow instability and complex strain in laminar conditions continue to form an important field of fundamental and applied research, presenting many pressing, yet unsolved problems, which have a major impact on energy production, transportation, the environment, and the economy. These problems are addressed in the broad range of research studies contained in these three volumes. The topics covered include: Bio-fluid Mechanics, Combustion, Compressible Flows, Experimental Methods, Fundamentals, Geophysical and Rotating Flows, Heat Transfer, Jets and Free Shear Flows, Magneto-hydrodynamics, Multiphase Flows, Numerical Methods, LES/Hybrid and URANS Methods, RANS Modelling, Separated and Aerodynamic Flows, Transition, Flow Control, and Turbulent Boundary Layers.
Over 320 extended abstracts were received and reviewed in a rigorous two-stage process by the members of the TSFP Advisory and Papers Committees. In order to avoid more than four parallel sessions, only 179 papers could be accepted for oral presentation. A further 28 papers were accepted for presentation in a poster session. Six leading scientists have contributed keynote lectures: Haecheon Choi (Control of flow over a bluff body), Petros Koumoutsakos (Bioinspired flow optimization), Robert Moser (Optimization as a vehicle for LES modeling in complex turbulent flow), Toshio Miyauchi (Laser diagnostics and DNS of turbulent premixed flames), Sutanu Sarkar (Compressible turbulence) and Cameron Tropea (Experimental investigation of a flapping wing model: Some challenges from unsteady aerodynamics).
The continued success of the TSFP Symposia is due to numerous individual contributions. We extend our sincere thanks to all participants of TSFP-5, who contributed their new scientific results, to the members of the Advisory Committee, who selected the most promising papers, and to the Local Executive Committee, whose members worked hard to ensure that TSFP-5 would be a scientifically successful as well as socially pleasant event. Finally, we gratefully acknowledge the financial support provided by AIRBUS Deutschland, ANSYS Germany, CD-adapco, DFG (German Research Association), DLR (German Aerospace Centre), EADS Astrium and GE Global Research-Europe.
