CFD Online Discussion Forums - Solid properties: thermophysicalPropertiesDict

Dear All,

I am gonna run a chtMultiRegionSimpleFoam case and I have a domain filled with air, in which there are 2 solids: a block of ice and a PCM that stays all around the ice.

I would like to understand if it is possible to model the phase changing in OpenFoam. How can I introduce the latent heat? And the temperature of this phase changing? Could you provide the right paramters (both for ice and for PCM) that should be inserted in this dictionary?

Thanks a lot,
Samuele
