The dynamics of transitional and turbulent flows is often dominated by organized structures with a life-time much longer than the characteristic time-scale of the surrounding small-scale turbulence. Organized structures may appear as secondary flows as a result of an instability, but they persist in turbulent flows. They manifest themselves as eddies or localized vortices and play an important role in, for example, mixing and transport processes. Although the existence of organized structures has been revealed by many experiments and by numerical simulations, they are somewhat elusive, as there is no consensus on how to define them and technically how to detect them. This volume contains reviewed papers from the IUTAM Symposium entitled "Simulation and Identification of Organized Structures in Flows" which was held in Lyngby, Denmark, on 25th - 29th May, 1997. The purpose of the symposium was to present the latest results from leading scientists within the field of detection and simulation of organized flow structures.Describing various aspects of complex, organized flow motion, including topics such as decomposition techniques, structure definition and recognition, experimental techniques and topological concepts, this volume should be of interest to all researchers active in the field.
