CONTRIBUTIONS TO THE UNDERSTANDING OF FLOW PULSATION LEVELS AND PERFORMANCE OF A TWIN SCREW COMPRESSOR EQUIPPED WITH A SLIDE VALVE AND A STOPPER FOR CAPACITY CONTROL.

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

Summary

THE PAPER DISCUSSES FROM A THEORETICAL VIEWPOINT THE FLOW PULSATION OF A TWIN SCREW COMPRESSOR AND HOW IT IS RELATED TO PERFORMANCE. THE COMPRESSOR IS EQUIPPED WITH A STOPPER IN ADDITION TO A SLIDE VALVE FOR CONTROLLING ITS CAPACITY AND THE COMPRESSION RATIO. THE VOLUME RATIO, THE FLOW CAPACITY, THE POWER CONSUMPTION RATE AND THE FLOW PULSATION LEVEL ARE DETERMINED BASED ON A GEOMETRICAL CHARACTERIZATION IN TERMS OF VOLUME VERSUS SHAFT ANGLE AS INPUT AND A THERMODYNAMIC ANALYSIS OF A SCREW COMPRESSOR FOR NO LEAKAGE. TYPICAL RESULTS ARE SHOWN FOR VARIOUS OPERATING CONDITIONS.
