Summary | 0003462: Inconsistency with functionObject wallHeatFlux | ||||
Description | I am simulating a combustion case with reactingFoam with openFOAM 7. For the boundary conditions on the temperature field, I am using "externalWallHeatFluxTemperature" in mode "flux" and I am taking into account the radiative heat flux (with a qrRelaxation). I post-process the wallHeatFlux in runTime by putting the function object in the controlDict and also after runTime by using "reactingFoam -postProcess -func wallHeatFlux". These two ways give me different results. I don't understand why and which one I should believe. I don't believe that this discrepancy come from the radiative heat flux which is not taken into account in one of the postProcess. | ||||
Steps To Reproduce | 1) run reactingFoam with the wall Heat Flux function object in the controlDict 2) after the simulation completion, run reactingFoam -postProcess -func wallHeatFlux 3) compare the results between the post-processing during and after runTime. | ||||
Additional Information | You can use this test case to see the problem | ||||

|
The wallHeatFlux functionObject is very simple and based on the wall temperature, it does not currently provide the same functionality as the externalWallHeatFluxTemperature BC. |
|
The wallHeatFlux functionObject could be updated to handle all the specific heat transfer BCs consistently but this would be complex and time consuming and requires funding. |
