Temperature Field Computation in the Stator of Air-Cooling Turbine-Generators Using the 3-D B-Spline Finite Element Method in Cylindrical Coordinates

摘要

The temperature distribution In the stator of air-cooling turbine-genertor is calculated using the 3-D B-spline finite element method in cylindrical coordinates. A three-dimensional wedge slice of a turbine-generator stator with windings Is chosen for modeling the problem. The B-spline finite element equations are established by employing the triple linear B-spline functions as basis functions. The results calculated for a 12MVA air-cooling turbine-generator are given.
