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. Last edited by meshingpumpkins; January 9, 2023 at 07:50. |

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. |
