相図に現したアトラクタ挙動による遠心圧縮機のサージ発生の予知(流体工学,流体機械)

抄録

The surge inception of a centrifugal compressor is studied by investigating the attractor behaviors in the phase portraits. The pressure time traces measured at the exit plenum of a compressor system are reconstructed on the phase portraits and the deformations of the attractors occurred preceding surge are shown. The possibility of detecting the surge inception by the proposed method is suggested.
