Hello,
I would like to give as input a heat flux in my fvOptions related to one region. This is the file I have: PHP Code:
Also, what do e and h mean on injectionRateSuSp? Thank you in advance! |

Hi,
If you switch volumeMode from absolute to "specific" the power will be in W/m³. But if you really want to specify heat flux in W/m² or even htc in W/ m².K on certainwalls you should use externallWallHeatFluxTemperature bc on the respective wall. Regards, Hussam |

Btw: h and e are the source terms for enthalpy and internal energy. Dependind on which option is selected in physicalProperties, the respective value stated in fvOptions/fvModels will be used.

Thank you for your reply! How do I add such a boundary condition? Do I have to add a new file on the desired region or can I add the script on an existing file (I am new in using OpenFOAM). Thank you! |

Hi, I would suggest to use the foamInfo utility, to help get more information about openfoam features. For this case:
"foamInfo externallWallHeatFluxTemperature" will return detailed usage information and examples from the tutorials about the topic. For this bc you can find an example in the tutorial "reverseBurner".. check it out. |
