PCM melting inside the Al cavity
Hello, I am modelling heat storage unit for electronic devices. It is basically aluminium enclosure open from the top and filled with phase change material (PCM). Heat sink with PCM heated from the bottom with constant heat flux. I managed how to model the solidification and melting, now I need to model thermal expansion of PCM during the melting. Does anyone knows how to do it? Shall I apply VOF model? There is an air above the PCM as well. So the interface between PCM and air should move up. Thank you in advance for help.
