AN EXPERIMENTAL INVESTIGATION OF PRESSURE DROP IN FORCED-CONVECTION CONDENSATION AND EVAPORATION OF OIL-REFRIGERANT MIXTURES.

Author(s) : TICHY J. A.

Summary

MEASUREMENTS OF PRESSURE DROP HAVE BEEN MADE FOR EVAPORATION AND CONDENSATION OF OIL-R12 MIXTURES INSIDE A HORIZONTAL T FOR CONDENSATION, A MODIFICATION OF THE PREDICTION GIVEN BY THE LOCKHART-MARTINELLI RELATION FOR FRICTIONAL PRESSURE DROP AND THE HOMOGENEOUS VOID FRACTION MODEL IS PRESENTED. FOR EVAPORATION, THE PREDICTION BY THE DUKLER II FRICTIONAL PRESSURE-DROP CORRELATION AND THE HOMOGENEOUS VOID FRACTION IS MODIFIED. THESE RELATIONSHIPS PREDICT THE PRESSURE DROP FOR 85% OF THE DATA TO WITHIN MORE OR LESS 35%. OIL INCREASED THE PRESSURE DROP 2 TO6% FOR CONDENSATION AND WITH 63 TO 86% FOR EVAPORATION.
