Abstract
In order to obtain effect of rotor rotation speed and inlet pressure on air mass flow rate distribution in various ducts of rotor of large turbo generators, the physical model of three-dimensional half axis rotor of 110MW air-cooling turbo-generator was created by the Gambit software. Then flow field of the model was simulated numerically according Finite Volume Method by the Fluent software. The effect of rotor rotation speed and inlet pressure on the distribution of air mass flow rate of axial inlet, end duct, sub-slot and radial ducts ventilation was analyzed. It shows that distribution of air flow rate in the rotor at actual working condition is different to experimental static condition and low inlet pressure condition.
