摘　　要：以典型的腔型/旋转结构为对象,采用CFX软件对腔内气相介质流动状态进行了分析,探讨了转动件转速、腔型/旋转结构轴向和径向尺寸以及腔壁润滑油膜速度等因素对腔型/旋转结构中气相介质流动状态的影响规律,并与国外的试验工作进行了比较。分析为腔型/旋转结构中油滴运动行为和油膜构成状态的研究、为腔型/旋转结构中两相介质流动物理性质的揭示提供了基础条件。The study of the airflow characteristic,based on the typical chamber-rotating structure,is carried out using the commercial code CFX 11.0.The results indicate that structural and conditional parameters,such as rotational speed of the rotating part,axial size and radial size of the structure and velocity of the oil film,affect the airflow characteristic.Finally,the results are compared with the results from the experiment found in reference.The analysis supplies a foundational condition for the study of the droplet flow behavior and the formed state of oil film and the understanding of the physical characteristic of the two-phase flow in the chamber-rotating structure.
