Abstract

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.
