That fluid flow states inside large generator stator radial ventilation duct is one of important facts which to decide the effect of stator ventilation and cooling, there is important significance to investigate. In this paper, the fluid movement differential equations are presented according to the theory of fluid dynamics, then the fluid field solved regions of ventilation radial duct with circular flow object or not is established respectively, the fluid fields are calculated numerically using finite volume method based on giving the corresponding solve conditions. The fluid flow characteristics inside ventilation duct with circular object or not are compared, the differences of fluid flow characteristic for the two ventilation structures are indicated, and some useful conclusions were achieved by which the theory foundation is established for large generator stator heat transfer characteristic.
