HEAT TRANSFER COEFFICIENTS AND PRESSURE DROP FOR FORCED CONVECTION BOILING AND CONDENSATION OF HFC134A.

Author(s) : FUKUSHIMA T., KUDOU M.

Summary

EXPERIMENTAL MEASUREMENTS OF LOCAL HEAT TRANSFER COEFFICIENTS AND PRESSURE DROP ARE MADE FOR FORCED CONVECTION BOILING AND CONDENSATION FOR R134A-OIL MIXTURES INSIDE A HORIZONTAL TUBE. THE RESULTS ARE COMPARED WITH THE EXPERIMENTAL DATA OF PURE R134A. AVERAGE CONVECTION BOILING AND CONDENSATION HEAT TRANSFER COEFFICIENTS DECREASED ABOUT 20% AT A 10% OIL MASS FRACTION, AND BOILING AND CONDENSATION PRESSURE DROP WERE 2.5 AND 1.4 TIMES THAT OF PURE REFRIGERANT FLOW RESPECTIVELY.
