| Abstract: | Based on three-dimensional unsteady actuator disk model,a three-dimens ional compressible unsteady model was developed to predict the stall inception a nd the effects of inlet distortion on performance and aerodynamic stability of c ompressor,and the effects of amplitude and frequency of rotating distortion on t he performance and aerodynamic stability of a two-stage low-speed axial compress or were analyzed using this model.The results show that both of the distortion a mplitude and rotating frequency will... |
