How to calculate heat transfer and solidification?
 

Hello,

I'm new with OpenFOAM. I have a case to solve which is as follows:

- There are three solid particles (dimensions about 1mm x 1mm x 3 mm). Between the particles there are little gaps (1mm) containing gas phase. At time t=0 there is a layer of hot liquid phase on top of particles.

- Hot liquid starts to flow between the gaps and around the particles due to gravity.

Schematic picture of the system is shown bellow.

- The problem should be calculated as three dimensional.



The main goals are:

1. Heat transfer to the solid particles caused by the hot liquid should be calculated to obtain a temperature profile.

2. Solidification of the liquid phase should be modelled.

Could this be modelled by adding heat transfer to some existing multiphase model? Is VOF-model useful for this kind of problem?

Is there anyone who could tell me how to get started? I'd appreciate it very much if someone could help.

Thank you,
