I want to calculate the pressure-distribution on my little house.
But the house is surrounded by trees. The trees have an effect on the
wind-flow, but it makes no sense to model the trees as solids.
I found this article
https://pdfs.semanticscholar.org/a0e6/9 ... fea0e1.pdf
They use darcy-forchheimer law for simulating the windbreak-effect of rows of trees.
Idea: use the porous-zone dialog in the cfd-wb.
But how must I interpret the input-dialog?
Is d=mu/k and f=1/k1 ?
What does the principal-direction mean?
When I estimate the „porosity“ k1 of a tree with 0,5, f=2.0. Is that right?
The vector e2 is missing in porosityProperties-dict.
I set up a turbulent test case, the „tree“ is the pink porous zone. I set the
turbulence-intensity to 15%, so I neglected the linear term in the darcy-forchheimer law.
Which gives zero for d in input dialog. Correct?
