The mechanism about "Late filling" ?

[xu-kai-xu]

@jgostick Hi, Jeff, i read the doc about the late_filling function in the .physics\multiphase.py file. I want to know the origin of the equation your team show in the doc:

$S_{nwp} = 1 - S_{wp}^{*} (P^{*}/P_{c})^{\eta}$

I also want to know how do you get the eta parameter for the equation. I wish you can supply some articles about this. I didn't find them in the doc.

Thanks a lot.
