GAS PULSATIONS IN TWIN SCREW COMPRESSORS. 2. DYNAMICS OF DISCHARGE SYSTEM AND ITS INTERACTION WITH PORT FLOW.

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

Summary

DYNAMIC TRANSFER FUNCTIONS BASED ON 4 POLE ARGUMENTS ARE FORMULATED FOR A TYPICAL DISCHARGE SYSTEM. VARIOUS MODELS, SUCH AS A LUMPED HELMHOLTZ MODEL, A ONE-DIMENSIONAL WAVE MOTION MODEL AND A THREE-DIMENSIONAL FINITE ELEMENT MODEL ARE DISCUSSED. AN ITERATING METHOD THAT COUPLES THE TIME DOMAIN CALCULATIONS OF PORT FLOW TO THE FREQUENCY DOMAIN TRANSFER FUNCTIONS IS APPLIED TO PREDICT PRESSURE PULSATIONS UNDER VARIOUS CONDITIONS. TYPICAL COMPARISONS TO EXPERIMENTAL DATA ARE SHOWN ALSO.
