A new wallBoiling heat transfer model has been added for use with the
thermalPhaseChangeMultiphaseSystem. This model operates similarly to the
alphatWallBoilingWallFunction. The difference is that the boiling generated by
the wallBoiling heat transfer model occurs on the surface of a third stationary
phase, within the volume of the simulation, rather than on a wall patch. This
can be used to model boiling within a packed bed or similar.
The wallBoiling heat transfer model and the alphatWallBoilingWallFunction share
underlying sub-models, so their specification is very similar. For example, in
constant/phaseProperties:
heatTransfer
{
...
bed_dispersedIn_liquid_inThe_liquid
{
type wallBoiling;
liquidPhase liquid;
vapourPhase gas;
heatTransferModel
{
type Gunn;
}
partitioningModel
{
type Lavieville; // phaseFraction, linear, cosine
alphaCrit 0.2;
}
nucleationSiteModel
{
type LemmertChawla; // KocamustafaogullariIshii
}
departureDiameterModel
{
type TolubinskiKostanchuk; // KocamustafaogullariIshii
}
departureFrequencyModel
{
type KocamustafaogullariIshii; // Cole
Cf 1.18;
}
}
bed_dispersedIn_liquid_inThe_bed
{
type spherical;
}
...
}
