DYNAMICS OF SCROLL SUCTION PROCESS.

Author(s) : NIETER J. J.

Summary

SCROLL COMPRESSOR SUCTION IS MODELLED AS A DYNAMIC PROCESS USING THE DIFFERENTIAL CONTINUITY AND STEADY, ISENTROPIC FLOW EQUATIONS. THE EFFECTS OF KINEMATICS AND FLOW DYNAMICS ARE PREDICTED AND SHOW THAT THE SUCTION GAS ACTUALLY STARTS TO BE COMPRESSED BEFORE THE OUTER SCROLL WRAP TIPS SEAL OFF THE DISPLACEMENT VOLUME OF GAS AT THE A THUS, IT IS POSSIBLE TO OBTAIN A LOCAL VOLUMETRIC EFFICIENCY, REFERENCED TO INLET CONDITIONS, OF GREATER THAN 100%. ACTUAL MASS FLOW MEASUREMENTS CONFIRM CYCLIC MASS FLOW RATES AT SUCTION WHICH ARE GREATER THAN THE TRADITIONAL IDEAL VALUE.
