Integral Length Scale vs Turbulent Length Scale

I have a paper that specifies an integral length scale, L.
The input option for fluent is for a turbulent length scale, l. The paper does not specify how the value, L, was measured, though I assume it was a trait of the turbulence grid. My question: is there a "standard" approach to convert L to l for use in Fluent. Granted this may not be correct, but at least it is standard. Thanks Scott |

I have the same question.
If I know that for external flow in area with low buildings L=140m. What turbulent length scale should I define in CFD? Paulina |
