HTC problem with multiphase

I would like to solve htc on a wall cooled by water jet (nozzle) and comparing to experimental tests.
When facing one phase (air), htc calculated is quite good.
When cooled with water htc is extremly high (1e4-1e5 W/m^2 K).
I tried several configuration but didn't find anything.
Lagrangian approach fails predicting very low htc, as the wall seems to be cooled by the entrained air.
Eulerian approch gives extremely high values (tried from laminar to sst with y+<1) using T bulk as Water temperature and wall with fixed temperature.
Suggestions are welcomed.
