The unsteady flow field of a high-load transonic compressor was numerically simulated at its working site

while the aerodynamic interaction of rotor-stator was analyzed in detail.Moreover

the unsteady global performance of this stage was discussed through the total pressure ratio and isentropic efficiency.Based on the static pressure coefficient

the profile pressure distribution and unsteadiness of rotor-stator interaction were analyzed to study the influence of trail and potential flow interference on the unsteady fluctuation for different blades.The results show that aerodynamic interaction has different influences on rotor-stator interaction

providing a further insight into the unsteady aerodynamic interaction of rotor-stator in a high-load transonic compressor.
