Dear Foamers,
I have a multiregion setup with a solid (=heater)/air/solid. Radiation heat transfer is needed. Between solid and air I want to use a coupled boundary for heat exchange. Before (=single region, no radiation) I could use groovy bc to read data from file like: Code:
... heater_to_airflow { type groovyBC; value uniform 1000; kappa solidThermo; kappaName none; timelines ( { name curTUpper ; outOfBounds clamp ; fileName "$FOAM_CASE/tempByTime.data" ; } ); variables ( "TTime=curTUpper;" ); valueExpression "TTime"; } ... When I use: Code:
... heater_to_airflow { type compressible::turbulentTemperatureRadCoupledMixed; Tnbr T; QrNbr Qr; Qr none; value uniform 1000; kappa solidThermo; kappaName none; neighbourFieldName T; } ... I also tried to set the internal field of the heater with build-in time-dependent boundary conditions, (http://www.openfoam.org/version2.1.0...conditions.php), something like: Code:
internalField uniform table ( ( 0 0.0) (1000 100.0) (0 200.0) ); Maybe somebody could give me a hint, how to enable a time depending temperature for coupled bc in this case? Thank you very much! dirk |
