This model describes a constant volume header with metal walls. The fluid can be water, steam, or a two-phase mixture.
It is possible to take into account the heat storage and transfer in the metal wall in two ways:
-
Leave InternalSurface unconnected, and set the appropriate
values for the total wall heat capacity Cm, surface S
and heat transfer coefficient gamma. In this case, the metal
wall temperature is considered as uniform, and the wall is thermally
insulated from the outside.
-
Set Cm = 0, and connect a suitable thermal model of the the
wall to the InternalSurface connector instead. This can be
useful in case a more detailed thermal model is needed, e.g. for
thermal stress studies.
The model can represent an actual header when connected to the model of a bank of tubes (e.g., Flow1D with Nt>1).
