Measurement of the Topology of Large-Scale Structures in Turbulent Reacting Flows

Turbulent combustion involves a complex interplay between fluid motion and chemistry. A widely held view is that large-scale structures play an important role in this interaction. Experimental work that concentrates on providing new information on the spatial characteristics of large-scale structures in flames has been done. Laser imaging techniques that can provide two-, and more recently, three-dimensional data on quantities such as species concentrations, temperatures, and densities in turbulent flames have been developed.
