The wavelet cross-correlation analysis is applied to the time signals of scalar concentrations deriving from axisymmetric direct numerical simulations of a coaxial jet flow. Indications are established on the contribution of the roll up, passage, and pairing of vortical structures to Reynolds stress and to mixing between the two streams.

Abstract
The wavelet cross-correlation analysis is applied to the time signals of scalar concentrations deriving from axisymmetric direct numerical simulations of a coaxial jet flow. Indications are established on the contribution of the roll up, passage, and pairing of vortical structures to Reynolds stress and to mixing between the two streams.File in questo prodotto:
