Historical Note


The International Symposium series on Turbulence and Shear Flow Phenomena (TSFP) is the successor to the highly regarded series on Turbulent Shear Flows (TSF) which started with its First Symposium at Penn State in 1977 and was run with great farsightedness, enthusiasm and success for 20 years by its founders Professors Franz Durst, Brian Launder, Frank Schmidt and Jim Whitelaw. When this team announced their wish to relinquish their organizational role after the 11th Symposium, held in Grenoble, France, in 1997, this news was received with great regret from all quarters of the turbulence-research community, for TSF had become an instantly recognized acronym for high-quality research and new discoveries in fluid-flow turbulence.

There seemed to be no doubt that TSF should continue in one form or another, since a missing follow-up Symposium would mean a major loss of a well established forum devoted to strengthening the interface between turbulence as a fundamental physical phenomenon and its role as a key ingredient in prediction schemes for solving problems in engineering and environmental fluid dynamics.

It was Professor Nobuhide Kasagi from The University of Tokyo who initiated discussions about the future post-TSF and who acted as the first chairman of the Organizing Committee of the TSFP series, the founding members of which were

  • John K. Eaton, Stanford University
  • Joseph A.C. Humphrey, Bucknell University
  • Nobuhide Kasagi (Chairman), The University of Tokyo
  • Michael A. Leschziner, UMIST
  • Martin Sommerfeld, University of Halle-Wittenberg.

The TSFP series began with a commitment to broaden the scope of the Symposium (compared with TSF) by integrating new and important areas such as industrial and environmental flows, bio-medical phenomena, non-linear chaotic systems, multi-phase and reacting flows, acoustics, and flow control. One of the new features of TSFP that were also planned was a series of review and panel sessions, in which the current status in key areas of turbulence and shear-flow research would be surveyed by leading experts. In this spirit, the Turbulence and Shear Flow Phenomena Symposium series started in Santa Barbara, California, in September 12-15, 1999, under the chairmanship of Prof. Sanjoy Banerjee who was co-opted to the Organizing Committee.
