    Abstract
  • A three-dimensional model for predicting compressor performance and stability was developed by solving N-S(Navier-Stokes) equation with source terms to annulus duct without blades.The source terms were calculated by flow field parameters which were generated by conventional three-dimensional computational fluid dynamics(CFD) solver at different operation conditions.A transionic single-stage compressor was investigated by the model with clean inlet.The three-dimensional flow field and performance of CFD results agreed well with those of the experiment,which indicat that the model is reliable and correct.Finally,the effect of circumferential total-pressure distortion on the compresser flow and performance was studied with the model.The compressor stability was further analyzed by introducing the stall criterion.
