Summary

AN EXPERIMENTAL STUDY HAS BEEN MADE OF BOILING HEAT TRANSFER ON A FINE HORIZONTAL WIRE IN REFRIGERANT-OIL MIXTURES WITH A RANGE OF PRESSURES UP TO 2.4 MPASCALS. IN THE CASE OF R115 WITH A SMALL SOLUBILITY FOR OIL, AN ANOMALOUS PHENOMENON APPEARS THAT THE HEAT TRANSFER COEFFICIENT DECREASES WITH INCREASING THE HEAT FLUX BEYOND A CERTAIN HEAT FLUX WHICH DEPENDS ON THE SYSTEM PRESSURE AS WELL AS THE OIL CONCENTRATION. IN THE R11-OIL MIXTURES, THE EFFECT OF OIL IS CONTRARY DEPENDING ON THE SYSTEM PRESSURE, THAT IS, THE OIL ENHANCES THE HEAT TRANSFER AT THE OIL CONCENTRATION BELOW 2 OR 3 WT% FOR 0.2 MPASCALS, BUT DETERIORATES IT OVER THE EXPERIMENTAL RANGE OF THE OIL CONCENTRATION FOR 0.1 AND 0.5 MPASCALS. THE INTENSITY OF THE EFFECT OF OIL ON THE BOILING HEAT TRANSFER DEPENDS ON THE TYPE OF OIL. (BULL. JSME, JP., 29, N 258, 1986/12, 4468.
