Work like this has already done with Enzo, in the realm of supersonic
turbulence . I wrote the code to calculate the structure
functions, and later modified to calculate them in an isolated
region. YT wasn't around then, so all of it is in a separate code- base, derived from the Enzo source.
If you're interested, I'm happy to share it, but I'll need to check
with Alexei Kritsuk (the lead researcher), first.
Let me know.

Dear fellow YT-users,
I would like to analyse turbulence in ENZO by comparing velocity
difference at different scales. To do this I would like to
calculate the velocity difference between each cell and cells a set
distance bracket away, square, sum over all cells, and square root
to get a turbulent velocity at that length scale. I would the like
to do that for many different length scales to form a graph of
turbulent velocity against length scale.
Has anyone ever done anything like this with YT or have a
suggestion for the easiest way to go about doing this? (with either
SH = 1 or 0)
