Mixing of two non-reacting gases

What is the best way to mix two non-reacting gases? If I were to have two streams (in my cases natural gas and steam, which have substantially different densities), how can I keep in from stratifying, even if it mixes?

A turbulent mixing layer? See the seminal work by Brown and Roshko (JFM, 1974) for details.

Sorry, I guess I was not completely explaining the problem. I have to make sure that my pressure drops are not much too. I was thinking about 2 shower heads, but the pressure drop in such a case will be huge.

John, thanks for the response. Do you know how I can generate the turbulence mixing layer in an industrial set-up at a minimal pressure increase.
