Hello everyone ,
I'm modeling the boiling in a straight pipe flow based on nucleate boiling tutorial . My inlet condition is 1 degree subcooled and I want to model phase change.
Heat Flux is induced on wall and I'm using RPI wall boiling.
Problem is whenever I try to simulate this case I get divergence.
If I'm away from saturation point in subcooled region then It gives some appropriate results as in nucleate boiling tutorial but my case here is to simulate pure phase change.
Can anybody here please help me simulate this case?
