【 摘 要 】

Our paper presents a combined method for the steady-state thermal field analysis from the turbo-generator rotor with the direct cooling. The thermal field analysis is made in two stages: 1) In the first stage, in order to determine the domain with the highest temperature, the thermal field is simulated by the thermal resistances and concentrated losses, 2) In the second stage, using the 3D finite difference method, we determine with a very good accuracy the point with the highest temperature from the rotor.
