Mixing: Kinetics and Geometry
Résumé
We review the different facets of the phenomenon of mixing, including its geometrical, temporal, and structural aspects. Then we suggest that a complex mixture can be viewed as the superposition of independent sources. Kinetics and geometry are shown to be closely linked to each other when following the transient mixing of an isolated scalar source in a turbulent flow. The composition law between multiple interacting sources is established experimentally, therefore allowing one to reconstruct any scalar field from well defined elementary contributions.
