MRF and Heat transfer calculation
 
I'm making the heat transfer calculation in an air-heater (there is a rotating section with metal construction). The flow calculation is correct when using multiful reference frame to calculate the rotation, but now the heat transfer calculation is not correct based on the analysis (I use the conjugate heat transfer calculation between solid wall and air, means the metal absorb the heat from the hot air, and then transfer to the cold air to heat up the cold air, the metal wall is build in the mesh as solid). So, I'm concerning if the thermal calculation can be performed in the MRF when the rotating section is important for the heat transfer? Or I can only use transient calculation with moving mesh in this calculation?

Has any body experiences on this type of calculation?

Thanks!
