Dear fellow researcher,
I have some problems when I try to run boiling heat transfer especially using RPI wall boiling model. My model is helically coiled tubes with the inlet that has been fully developed profile by using single-phase flow then proceed with the boiling model with RPI wall concept. I choose this term because it said in FLUENT it is the best method to capture the boiling near the wall. On this case, my goal is to understand the behavior of subcooled boiling heat transfer in the domain.
But I have got the problems on the IAC (interfacial area concentration) and this parameter got diverged at the iteration more than 1000. Please provide me some resource to troubleshoot this particular problem.
FYI, I am running the simulation with steady-state solver.
