| 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; | |
| } | |
| } | |
