Implementation of the superfluid helium phase transition using finite element modeling: Simulation of transient heat transfer and He-I/He-II phase front movement in cooling channels of superconducting magnets

► Transient and steady-state temperature distributions along 1D He-II channels are calculated. ► Non-linear Kapitza conductance is implemented by using boundary integration variables. ► Phase front movement during sub-cooling of long helium channels is modeled using the ALE method. In the thermal de...
