It means statistically steady, e.g. the energy spectrum or any other statistical measure of the flow is steady. It does, however, require that there be some forcing so the energy being put in can be balanced by the energy dissipated by the viscosity, so nlooije's equation needs to be supplemented with another term representing that force. (Sorry, nlooije, you didn't invent it! ;) ) | |

render reynolds number in roman rather than italic font, replace >> with \gg and << with \ll, insert some whitespace in appropriate places.

| Aug 5, 2015 at 15:53 | comment | added | nluigi | @Bernhard I knew someone would comment on that :)... You are right, turbulence is inherently unsteady of course. But for the sake of not having to define a characteristic time scale as well and keeping it as simple as possible, I have invented steady turbulence. | |
