GAS PULSATIONS IN TWIN SCREW COMPRESSORS. 1. DETERMINATION OF PORT FLOW AND INTERPRETATION OF PERIODIC VOLUME SOURCE.

Author(s) : KOAI K. L., SOEDEL W.

Summary

FLOWS THROUGH THE SUCTION AND DISCHARGE PORTS OF A SCREW COMPRESSOR ARE OSCILLATORY IN NATURE. THE PAPER UTILIZES THE VOLUME AND PORT AREA CURVES BASED ON ROTOR PROFILES AND OTHER GEOMETRIC DATA FOR A TYPICAL TWIN SCREW COMPRESSOR. THE GAS CONDITIONS AND PORT FLOWSARE DETERMINED FROM THERMODYNAMIC ANALYSIS FOR A COMPLETE CYCLE OF DISCHARGE AND SUCTION ACTIVITY. THIS INCLUDES THE CONDITIONS OF UNDER-AND OVER PRESSURE. TYPICAL FOURIER SPECTRA FOR PORT FLOW ARE PRESENTED.
