Hello everyone

I am trying to calculate integral length scale in Fluent for a fluidic oscillator. My objective is to carry out LES simulation.
I am using the expression :

integral length scale l0 = k^1.5 /e where k - turbulent kinetic energy and e is eddy dissipation.
During post processing maximum and minimum values of turbulent kinetic energy and eddy dissipation rate is given. Can these values used to determine integral length scale.

If not what is the process to determine integral length scale?

Thank You
