IUTAM Symposium: Laminar-Turbulent Transition
Abstract
The origins of turbulent flow and the transition from laminar to turbulent flow are among the most important unsolved problems of fluid mechanics and aerodynamics. Besides being a fundamental question of fluid mechanics, there are any number of applications for information regarding transition location and the details of the subsequent turbulent flow. The IUTAM Symposium on Laminar-Turbulent Transition, Co-hosted by Arizona State University and the University of Arizona, was held in Sedona, Arizona. Although four previous IUTAM Symposia bear the same appellation (Stuttgart 1979, Novosibirsk 1984, Toulouse 1989, and Sendai 1994) the topics that were emphasized at each were different and reflect the evolving nature of our understanding of the transition process. The Sedona 1999 meeting focused almost exclusively on open systems, and as such, on wall-bound shear flows. The major impact topics were receptivity of initial disturbances, cross flow instabilities, supersonic flows, and control of transition. Many papers were on combined numerical and experimental work. The objectives of many of these studies were to properly define the fundamental physics of the stability and transition process. As a consequence, this fundamental knowledge now enables different techniques of transition control and its subsequent decrease in drag. One expects increased emphasis on this topic in the future.
