I am trying to simulate a simple bar (region1 "R1" copper) which is connected with another bar ("R2" copper)

in the first step i would like to simulate only heattransfer from one side (400K) to the other side (300K) (rest is adiabat)

In the second step i would also account joule heating including an electric contact resistance.

for validation i used to do the simulation with and without resistance and also using only one region of copper for the whole bar....so no interface is present

solver: chtMultiRegionSimpleFoam

for the interface boundary condition i used: compressible::turbulentTemperatureCoupledBaffleMix ed

i was trying to emulate the resistance of contact with kappaLayer setting but if i compare my results with theory i would conclude that there is something wrong with my results. Has anyone any idea or experiance with contact resistance between solids in openfoam?


I am using the esi version v2112.

dear all!

i went to foundation version 9 and the results are like they should be compared to theory....

so there is some difference between esi and foundation with using
kappalayers.
