I think it would be great if we could have a phase change in multiphase flow simulations. a few examples of use cases are:
- Pouring a mould and solidifying of the material (expect the material to shrink within the mold as it is cooling)
- external flow with Ice build up on a wing (possibly local time stepping due to time it would take in sim time?)
- Steam production from a boiler (more accurate heat exchanger sim including LH of evaporation)
Unfortunately, this is a little harder as to my knowledge there is no thermal model in Multi-Phase flow? So this might have to be implemented first?
This is something I have wanted to do for a while, however, yesterday someone commented on one of my projects and asked about icing simulations and it got me thinking.
I would expect geometry wise that the ice build up would be treated as a liquid would be in terms of its phase boundary being defined as a fraction.
Any thoughts and ideas on this are appreciated and I understand this might be a bit of a tall order.
