Turbulence Modeling and Vortex Dynamics

This volume collects contributions to the workshop on "Turbulence Modeling and Vortex Dynamics, Istanbul", where engineers, physicists, and mathematicians discussed the statistical description of turbulence. They cover practical aspects as well as rigorous mathematics. This book will be a source of reference for many years for those working in this most fascinating field of scientific modeling.
