about eulerian boil model
 

Dear all,
My work:boiling in horizontal tube.
Model: Eulerian.
My question:
There is an option named boiling in multiphase-eulerian tab in fluent 15.0. I f I use this model, should I add the udf like the classical boil udf in the tutorial to change the source term?

Boiling
 

for boiling there are RPI, Critical Heat flux and Non equilibruim boiling methods, if your heat flux is constant value you dont need UDF.
goodluck
