Foam::fv::heatExchangerSource
|
||||
|
||||
Description
|
||||
Heat exchanger source model.
|
||||
The total heat exchange is given by:
|
||||
|
||||
Qt = e(phi, secondaryMassFlowRate)
|
||||
* (secondaryInletT - primaryInletT)
|
||||
* phi*Cp;
|
||||
|
||||
where:
|
||||
e(phi, secondaryMassFlowRate) is a effectivenes table in function of
|
||||
mass net flux coming imto the heat exchanger (phi) and
|
||||
secondaryMassFlowRate
|
||||
|
||||
Then the distribution inside the hear exchanger is given by:
|
||||
|
||||
Qcell = V*Ucell*(Tcell - Tref)/sum(V*Ucell*(Tcell - Tref));
|
||||
|
||||
where:
|
||||
Qcell is the source for cell
|
||||
V is the volume of the cell
|
||||
Ucell is the local cell velocity
|
||||
Tcell is the local call temperature
|
||||
Tref : min(T) or max(T) in the cell zone depending on the sign of Qt
|
||||
|
||||
Example :
|
||||
|
||||
heatExchangerSource1
|
||||
{
|
||||
type heatExchangerSource;
|
||||
active true;
|
||||
selectionMode cellZone;
|
||||
cellZone porosity;
|
||||
|
||||
heatExchangerSourceCoeffs
|
||||
{
|
||||
fieldNames (e);
|
||||
secondaryMassFlowRate 1.0;
|
||||
secondaryInletT 336;
|
||||
primaryInletT 293;
|
||||
faceZone facesZoneInletOriented;
|
||||
outOfBounds clamp;
|
||||
fileName "effTable";
|
||||
}
|
||||
}
|
||||
|
||||
Note:
|
||||
the table with name "fileName" should have the same units as
|
||||
secondaryMassFlowRate and kg/s for phi
|
||||
faceZone is the faces at the inlet of the cellzone, it needs to be
|
||||
created with flip map flags. It is used to integrate the net mass flow
|
||||
rate into the heat exchanger
