Turbulence parameterization from gravity - fluid dynamics correspondence

Physics Asked by Dilaton on January 26, 2021

I`m looking for a nice introductary reference that explains how the turbulence coefficient or any kind of turbulence parameterization (in view of applications to atmospheric turbulence for example) can be derived from the gravity – fluid dynamics correspondance, such that even I can get it. I mean, if something like this exists …

I`m basically quite familiar with the hydrodynamic part (NS equation, etc) of this correspondance whereas about the other side I feel a bit more shaky …

I`m finally looking for a citable reference, but any “reasonable” source (slides of a talk, video, ect) that explains how a turbulenc coefficient / parameterization can be obtained would be welcome and appreciated.

Edit

To clarify what I mean, relevant papers for the topic are for example here, here, and jep this one linked to by Mitchell.

One Answer

I assume you mean the critical exponents of the velocity correlation functions? First of all, I don't think they have been derived using fluid/gravity (this is a very difficult problem), at best the problem was mapped onto a different problem. There was a series of papers by Oz and others about incompressible (and compressible) Navier-Stokes some years ago, see for example http://arxiv.org/abs/0905.3638, http://arxiv.org/abs/0906.4999, http://arxiv.org/abs/0909.3574. There are also somewhat more handwaving efforts like http://arxiv.org/abs/1005.3254.
