The current version of twophaseeulerfoam

Hi everyone, I would like to know the current version of twophaseeulerfoam is based on which researcher's algorithm?Alberto Passalacqua or Henrc Rusche? Thnak you.

The original one is implemented by Henrc Rusche. Later it was extended by Henry Weller.

Thank you a lot. But I cannot find the document regarding Henry Weller but only Rusche.
So the solution algorithm of Passalacqua is not yet implemented in the current OPENFOAM? 
@kimy 在 The current version of twophaseeulerfoam 中说：
So the solution algorithm of Passalacqua
Reference?

@李东岳 yes. but I found some authors already refer the following paper with respect to current twophaseeulerfoam.
such as

The highlight says that openfoam23x adopted the conservative formulation. More details about the conservative formulation can be seen in Alberto's paper.

Thanks a lot. I wonder if the partial elimination algorithm mentioned in Passalaqcua's paper was implemented in the current version?
