  • 摘要:In the rotor with high speed, there is a certain axial circulation in the internal gas, which is necessary to analyze the cause of formation and influence factors for understanding better the internal flow field. There are many factors affecting the axial circulation. Different circulation drives have different effects on the flow field. In this paper, numerical computation with N-S equations is used to compute the flow field parameters and analyze the mechanism of the flow field. The influence of the temperature of the end cap on the flow field is mainly disscussed. By comparing and analyzing the streamline shape and the size of vortex region under different temperature drive, an effective method is provided for the study of axial circulation in the highspeed rotating flow field.
