| 摘 要： | 为了探索周期性射流的射流状态转换过程中转子流场的动态响应特征,采用非定常数值方法对转子流场进行了模拟,并对叶尖泄漏涡的运动规律和转子负荷分布的动态变化进行了分析.结果表明,转子流场的响应主要表现在两个时间尺度:①与叶尖泄漏涡振荡周期相当的小尺度;②与转子负荷径向分布变化相关的大尺度.

| Abstract: | The purpose of this work is to study the dynamic response characteristic of the rotor flow field during the transition between injection entrance and quit state.The rotor flow field was numerically simulated with an unsteady method.The motion of the tip leakage vortex(TLV) and the dynamic variation of rotor loading distribution were analyzed.It is concluded that,the response of the rotor flow field has two types of time scale,one is small corresponding with a scale of TLV fluctuation,and the other one is large and correlated with the changes of radial distribution of the rotor loading. |
