Dear all
I am working on modeling and simulation of film boiling formation on hot rod when submerging in water. I use flow3d models so that use the adiabatic bubble model with heat and mass transfer. through, I use Clausius-Clapeyron model and found thermodynamic data which need for this model such water saturated pressure, latent heat vapor, accomodation coefficient and etc. then i enable the cavitation model for initiation of bubble, the result of model processing is not logical. For example the bubbles form an different place, but we excepted that bubble form only on hot surface of rod, also the pressure was not logical. I think there are any problem in cavitation properties in physics section also I have not confident on accomodation coefficient (I examined with 0.1 and 0.05 values). Would you please guide me for this problem and where are there any mistake for this model.
