NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. Experiments have been performed in turbulent shear layers to assess the effects of Reynolds number on mixing. The experiments extend the upper range of incompressible, chemically-reacting flow data from [...] to [...] and, in a subsequent collaboration with M. Slessor and others, to 7 x 10[...]. The experiments address an ambiguity in recent measurements of mixing in compressible shear layers, whose differences from measurements in incompressible shear layers could have been due either to compressibility or Reynolds number effects. The current results, collectively with previous results, show that the decrease of mixing with increasing Reynolds number first seen by Mungal et al. (1985) continues to the Reynolds numbers studied, but do not show a further decrease in mixing. The conclusions must be tempered by the presence of changes in the initial boundary layers and acoustic environment, and by the compressibility ([...] = 0.25) of the highest Reynolds number (Re = 7 x 10[...]) case.
