The first detailed, quantitative study of the 2-D mixing layer was completed by Liepmann and Laufer in 1947. They described this technologically important flow in terms of the variation of the mean velocity and various mean fluctuation intensities. The measurements were of high quality, and have scarcely been improved upon in the intervening forty years. Yet they give very little fundamental understanding of the structure of the flow. What has changed within the past twenty years is the increased concern with process in turbulent flows. Today turbulent flows are perceived to contain identifiable structure. The interaction of structure is the turbulent process. Thus process attempts to provide a dynamical description of the flow, and is a more ambitious undertaking than a simple description of the state of the flow.
