Modern experiments and numerical simulations show that the long-known
coherent structures in turbulence take the form of elongated vortex
tubes and vortex sheets. The evolution of vortex tubes may result in
spiral structures which can be associated with the spectral power laws
of turbulence. The mutual stretching of skewed vortex tubes, when they
are close to each other, causes rapid growth of vorticity. Whether this
process may or may not lead to a finite-time singularity is one of the
famous open problems of fluid dynamics.
This book contains the proceedings of the NATO ARW and IUTAM Symposium
held in Zakopane, Poland, 2-7 September 2001. The papers presented,
carefully reviewed by the International Scientific Committee, cover
various aspects of the dynamics of vortex tubes and sheets and of their
analogues in magnetohydrodynamics and in quantum turbulence. The book
should be a useful reference for all researchers and students of modern
fluid dynamics.
