摘要：In order to study the impacts of the stator ventilation structure on the thermal performance, the fluid flow model of the stator radial ventilation ducts is established. The fluid flow fields are calculated and analyzed, from which the three-dimensional fluid field distribution inside the radial ventilation ducts is shown. Subsequently, the heat transfer coefficients are obtained on the basis of calculated results of the fluid flow field, and the stator three-dimensional temperature fields are solved. The numerical results are compared among different inlet velocities at the entrance of the radial ventilation ducts, which provides a theory basis for the design of the cooling system and improves the safe operation level of the generator. © (2013) Trans Tech Publications, Switzerland.
