Hello all of you,


I am looking for the d and f coefficients of the Darcy-Forchheimer equation for some typical trees (like oak).
In some places I hear that d=0 for trees and that f is around 0.13 for an oak tree. But is that true? Using these values I get unexpected results, aka resulting in a seemingly too high porosity.


Do people have typical d and f coefficients for some tree species?


Thanks for hints/ideas/links.


All the best,


Victor
