We carry out direct numerical simulation (DNS) of scalar transport and mixing in a coaxial jet issued into a small model combustor. Analysis is made on the detailed mechanism of mixing enhancement achieved by an active control of the near-field large-scale vortical structures. The main interest lies in the relationship between these vortical structures and associated scalar transport processes in the near field downstream of the nozzle exit. From the phase-averaged statistics, the mechanism of mixing enhancement is revealed in the case of the best mixing achieved.
