compressibleInterFoam/compressibleMultiphaseInterFoam mathematical equations
 

Hello,
the purpose of this thread is not to ask how to use the mentioned solvers, rather I am looking for the mathematical equation solved by these solvers.

I have found for instance the mathematical equations for the "interFoam" solver. where the continuity and momentum equations are described. see the link:
https://openfoamwiki.net/index.php/InterFoam

but unfortunately I couldn't find anything for "compressibleInterFoam" nor "compressibleMultiphaseInterFoam"

if you know a reference that could help me, it would be very nice of you to mention it.

thank you for you time!
