Effects of 3D Flow on Aerodynamic Stability of Axial Flow Compressor

  • Received Date: 02 Sep 1996
  • Publish Date: 28 Feb 1998
  • Concerning the models for discribing aerodynamic stability of axial flow compressor,the original model is onedimensional,and it is reasonable for the onset of surge only.For the onset of rotating stall,there are just some twodimensional models at published literatures.A threedimensional aerodynamic of compressor has been presented in this paper.An aerodynamic stability model concerning radial disturbance of compressor is presented.The calculated results show that the occurrence of radial disturbance is related to the axial velocity disturbance,which has important effect on aerodynamic stability of compressor.The position of onset of stall,in blade tip or hub,is dependent upon the characteristics of blade element.The comparisons of calculated results predicted by 2D and 3D aerodynamic stability model have also been made in this paper.
