Hi,

I am trying to simulate pool boiling in OpenFOAM v.11 using multiphaseEuler. I am trying to understand how to set up the boiling physics. As far as I understand there are two main ways of doing this:

1) Through 0/alphat and using alphatWallBoilingFunction.
2) Through constant/phaseProperties/heatTransfer/ and using the wallBoiling type.

I think method 1) will only work with a turbulence model specified and method 2) is for fluidized beds (solids particles as the third phase). However in my case of pool boiling I would like to simulate the phenomenon without a turbulence model. How would one set this up in a laminar simulation? Or would the cell-to-wall distance have to be so small that it would be unpractical to solve this and therefore they have not implemented this?
