We perform Large-eddy simulations (LES) of turbulent variable-density jets. A fully developed turbulent pipe flow of air at the Reynolds number of Re = 5300 enters a large reservoir of air, helium or carbon dioxide. The impulsely starting jets as well as the fully developed stationary flows are considered. In the first case we show that the air stream propagates faster in the light medium of helium as compared to other gas pairs, while in the fully developed case the same helium-air pair exhibits the lowest level of turbulent fluctuations.
