Turbulent mixing in non-reactive and reactive flows

This volume presents the current status of several facets of the problem of turbulent mixing. The papers are the outcome of a workshop type conference on turbulent mixing organized by Project SQUID. A paper (also invited to the workshop) outlining some aspects of the 1974 Southampton Colloquium on Coherent Structures is included. In order to provide a background to the discussions at the meeting, a review was written to examine in some depth the status of the subject and it is presented here as a position paper on turbulent mixing.
