| Abstract: | In order to analyze the characteristics of fluid-flow of the stator of a high speed non-salient-pole synchronous machine,the three dimensional(3-D) mathematical and physical models of stator including stator end,iron core and air-gap for fluid analysis were established,which were calculated numerically by using computed fluid dynamics(CFD) software named Fluent,based on some corresponding boundary conditions and assumptions.In this process,the fluid velocity distribution characteristic of the stator ventila... |
