chtMultiRegionFOAM: variableHeatTransfer - htc-Field/Visualisation
 

Hello everybody,


i am recently looking into chtMultiRegionFoam and doing some Simulations with it.
In my Simulation (similar but simpler like the heatExchanger in tutorials) i want to use the variableHeatTransfer to simulate a velocity-depend heattransfer (convective Heattransfer) between a solid and fluid region.
To do so i changed in fvOptions the type from constantHeatTransfer to variableHeatTransfer.

VariableHeatTransfer calculates the Nusselt-Number according to:

Nu = a * Re^b * Pr^c

and based on the Nu-Number it calculates the htc-value.


In order to controll my Parametrization of the Nu-Number-Calculation (a,b,c) i want to save the calculated htc-value and/or Nu-Number for postProcessing into a file.


According to the variableHeatTransfer.C-file a volScalarField is used to calculate Nu, htc and Re.

So does anybody know if any of the mentioned volScalarFields are already saved and can be used for postProcessing?


And if not, i will try to extract the htc-value for postProcessing.

Because this a quite general question i didnt provided the a simplified case here but if you are interessted i will provide a simplified Sim-case for a futher look into my described problem.









Many Thanks in advance
