Foreword

Turbulent flows are known to contain a wide range of scales, with different physics operating in different sub-ranges. For instance, the energy dissipation takes place at small-scales. Yet, the process is linked to the large scales of the system, which carry most of the energy. A general interest clearly exists in the problems just mentioned if only because turbulence is a paradigm for the behaviour of systems with many degrees of freedom. In comparison with other problems of condensed matter and complexity, turbulence is a relatively clean system whose lessons, if based on solid foundation, can be of greater value.

The basis for expecting the near-universal behaviour of small scales is Kolmogorov's theory (1941 and 1962). Nowadays, the gaps in this theory are becoming increasingly certain. To establish possible consensus of the new and post-Kolmogorov ideas, this Euromech Colloquium was organized, to deal primarily with the non-universality of the small scale dynamics.

Given the emphasis on similar topics in geophysics, stellar physics, MHD and plasma dynamics, perhaps even in cosmology, we think that the contents of the Colloquium can be of interest to a number of communities. The question of whether a universal state exists independent of the forcing, or of the aspects in which the latter effects continue to be felt, is the core of research in several of these areas. The advances made in turbulence proper in these directions are significant enough to be able to take stock of the situation with some clarity.

The readership of these Proceedings is expected to be interdisciplinary between physics (general physics, mathematics and statistics, earth and atmospheric sciences, astrophysics, plasma physics), and engineering (fluid dynamics, aerodynamics, environmental engineering, chemical engineering).
