Thermal Conductivity in reactingFoam

pspk · April 28, 2022, 01:26

I am using reactingFoam solver with Sutherland Transport. I'm aware that Sutherland also calculates thermal conductivity k, from viscosity and specific heats. Can anyone tell me how to extract that thermal conductivity as a result in the simulation along with other properties like T and U?

To visualize, post-processing in e.g. Paraview can be employed.

I understand your problem to be that you are having difficulty writing the thermal conductivity field as a result at all since your solver probably is not writing it per default.

If that is the case, have a look at the writeObjects functionObject. There you should be able to specify the alpha field or any field present in the object registry for that matter.
