Abstract
Using laser imaging data for scalar mixing collected in turbulent jets of Frcon-12, synthesised images are generated for reaction zones in turbulent nonpremixed flames of hydrogen at high Damkholer numbers. It is found that Quasi-Equilibrium Distributed Reaction (QEDR) zones govern the flame structure except in the first fifteen jet diameters near the nozzle. This structure which otherwise follows the stoichiometric mixture fraction ξ, tends towards that of scalar dissipation, χas the distance from the nozzle increases.Keywords
