Steady-State Thermal Field Analysis from the Turbo-Generator Rotor with Direct Cooling
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.
