turbulence length scale?
 
Hello,

I am using a non-commercial LES code and need to calculate free-stream turbulence length scale. I know the theory (i.e. the spacial correlation concept) but I need some hints on how to implement and output the data for length scale calculation. Anyone could help please? :confused:

Hi,
in turbulence there are more than only one characteristic scale ... what do you want to know, Kolmogorov, Taylor, integral scale?

thanks, for free-stream turbulence I think we are concerned with integral scale, I would also appreciate any hints on other scales though.

I suggest a reading of such topics in the book of Pope
