Taylor microscale
has anyone calculated taylor microscale in openfoam?
Appreciate it if you share the code. 
any one has any Idea?

People might be more likely to help if you provide a little more information e.g. equations; sources; what you have tried already; what type of simulation your are performing. I'm interested in the topic if you can provide more details.

thanks for the interest chegdan,
Taylor microscale is the main length scale measured in turbulent homogeneous box to determine Reynolds number since there is no physical length scale. here is a more descriptive of what it naturally is: http://en.wikipedia.org/wiki/Taylor_microscale but a formula to calculate it is presented in "turbulent flow" by Pope in page 199. Can you tell me how to put that formula in Opefoam?
