Hello, I am trying to solve a 1D heat analysis problem for an electric generator. The stator or the device icludes the copper which is well insulated and is cooled from the left using water running through a pipe. The rotor is made of magnets supported by an iron frame. Cooling air is blown through the narrow gap between the rotor and stator. I am using the equations of conduction with thermal energy generation to solve this problem. However, all the exampes in books show problems with only the one side of the device to be cooled. Any suggestion on how i should work on that?
