“…The selection of empirical correlations is a realistic and fast method to obtain the heat transfer coefficient, but careful attention should also be paid to the applicability of the chosen correlations. Besides, evaluation of the heat transfer area of the end winding is also a complex task [96].…”

This paper presents a coupled fluid-thermal network modeling approach. Thermal conduction and convection and interaction with the air flow are modeled. Special emphasis is put on a modular model so that geometry and cooling methods can be simply modified. The structure of all necessary modules is introduced. To demonstrate the abilities of this modeling approach, a network involving a 6 MW synchronous machine with cylindrical rotor with directly cooled conductors and a rotor with indirectly cooled conductors is generated and the results are investigated.
