Hi,


I want to find the heat transfer coefficient and to calculate that, I used the heatTransferCoeff as the function type in my control dict. However, when I run it with ChtMultiRegionFoam it gave me an error by saying that the heatTransferCoeff function is not available and only available is wallHeatTransferCoeff. However, the wallHeatTransferCoeff function is only working with the Reynolds analogy type. But I want to use the heat transfer coefficient with the fixed reference temperature. Therefore, is there anyway that I can use wallHeatTransferCoeff with fixed reference temperature ?


Many thanks in advance.


TGS

Check that you have the right version of foam. Any version that has heatTransferCoef will also not have wallHeatTransferCoef


You have to calculate it yourself. Use wallHeatFlux together with T and setFields or compile your own heatTransferCoef library (copy and paste the code and build it on your version).

Hi Tran,

Thank you very much for your advise. Could you please let me know if possible, what is the mathematical equation which is associated with wallHeatFlux equation? Is that the equation calculate the total heat flux values on the total surface ? I mean all cells in that surface?

Thanks.

I will do you one better and tell you that you can find the code for all all of them in
