\subsection{Porosity parameters}
|
||||
Several parameters should be calibrated in order to accurately model the porous media: $a$, $b$ and $c$ are friction
|
||||
parameters in Forcheimer's equation; D50 is the median diameter of the elements constituting the porous media; $p$ is
|
||||
the porosity of the media.
|
||||
|
||||
7 cases were run with the values in \autoref{tab:porotest}.

between cases (excepted for case 3, where $b=0$).
