Look carefully at the flow as the divergence approaches. Whilst some of the boiling models are allegedly steady state the resulting multiphase flow usually isn't.
Also, whilst the mesh has y+>30 how does the aspect ratio look? It's a failing in most of the text books: everyone is told about cell aspect ratio, but then doesn't realise that inflated meshes always have a high aspect ratio. That's OK if the solution doesn't change along the cell; this never happens in multiphase.....Â
