Volume Fraction Eq for Secondary Phase/Cavitation
 

Dear all,

I am writing a mathlab code to compute pressure drop and temperature variation through a pipe where cavitation occurs.
At this regard, I need to know the volume fraction of vapour phase and I was thinking to iterate the eq 17.121 of ANSYS Fluent Theory Guide (Release 15) in order to have that.
The issues are:

1) How can I use it in Lumped Method Approach?
2) How can I compute the two mass flow contributio (mpq and mqp)?

Thank u so much :D

Here u can find the formula I am talking about!
