Class
Foam::fv::interRegionHeatTransfer
Description
Model for inter-region heat exchange. Requires specification of a model for
the heat transfer coefficient (htc) and the area per unit volume (Av).
These are then used to apply the following source to the energy equation:
\f[
-htc*Av*(T_{nbr,mapped} - T)
\f]
If the semiImplicit option is set, then this becomes:
\f[
-htc*Av*(T_{nbr,mapped} - T) + htc*Av/Cp*h - Sp(htc*Av/Cp, h);
\f]
Usage
Example usage:
\verbatim
interRegionHeatTransfer
{
type interRegionHeatTransfer;
libs ("libinterRegionFvModels.so");
nbrRegion other;
owner true;
interpolationMethod intersection;
semiImplicit no;
Av 200;
heatTransferCoefficientModel constant;
constant
{
htc 10;
}
}
\endverbatim
