In metal I know that the conductivity is due to the electrons and do you
know that if the system temperature is about Debye temperature order and for
graphite it is 645K, the conductivity is only
occurs via phonon… what I want to is inverstigation of the interface of silver
wall domain and water heat transfer. The wall consist of silver and one side
of wall is hot and one side is cold and inverstigating
how the water is acting between them. And if I use that kind of high
temperature, water is not liquid anymore, as have vapor layers.
Do you have any idea about how should I model it? and how should i choose the timestep for graphite?
