摘要

A series of laser Rayleigh-scattering experiments has been performed to investigate the effects of differential molecular diffusion in turbulent nonreacting jet flows. A turbulent jet of a mixture of Freon and H_2 exiting into coflowing air was studied at various Reynolds numbers. In laminar flow, Rayleigh scattering clearly showed H_2 diffusing ahead of Freon. In turbulent flow, the instantaneous Rayleigh images showed differential diffusion at the many interfaces between jet fluid and entrained air. Yet, ensemble averages of instantaneous images showed no average diffusion of H_2 ahead of Freon.
