The present investigation builds on the work of Khorsandi et al. [1], who studied the velocity field of a turbulent jet emitted into a turbulent background. We examine herein the effect of an approximately homogeneous, isotropic, zero-mean-flow turbulent background on the scalar field of a turbulent jet. To this end, we measured the concentrations of a high-Schmidt-number passive scalar within the jet by means of planar laser-induced fluorescence. We present the statistics of the jet’s scalar field and compare them with the results of a jet emitted into a quiescent ambient.
