I want to simulate 2D pool boiling in Ansys fluent using Eulerian model. Most of research papers available uses VOF model for simulation but there is no information regarding Eulerian RPI boiling model for pool boiling. I tried but there are some issues regarding simulation

1) Continuity equation is not converging below e-03.

2) Confusion regarding interaction models for drag, lift, wall lubrication etc.

3) In animation, there are no vapor bubbles visible

I will appreciate if anyone can give suggestion for these issues and provide some tutorial or research paper of 2D Pool Boiling Simulation Using Eulerian Method (water as fluid)

Computational domain

2D rectangular domain with length 30mm and height 50mm. Turbulence modelling is included with K-e model.

BC,s

Top - pressure outlet at atmospheric pressure

Left and Right walls - Adiabatic

Bottom - At Temp of 380K or more (above 373.15K)
