Abstract
This paper has focused on the problem of mixing and mixing assessment. The K-L procedure applied to data collected from a jet in crossflow provides optimal bases for the analysis of the flow. It is found that better mixed flows are characterized by the dominance of spatially complex eigenfunctions. Qualitative measures of the complexity are presented and it is anticipated that this technique will provide a sensitive metric of the mixedness of flows in a wide variety of applications.
