Nucleate pool boiling heat transfer of new, environmentally harmless refrig
erant mixtures R32/R125 has been systematically investigated in a wide rang
e of pressure and heat flux under saturation conditions using a horizontal
platinum wire (d = 0.1 mm). The platinum wire served as both heating elemen
t and resistance thermometer. The experimental results are compared with ca
lculated values using a modified Jungnickel correlation. The comparison bet
ween all calculated data and experimental data shows good agreement. Most o
f the data fall within +/-20% of the correlation. The mean average deviatio
n is +/-8.25%. (C) 1999 Elsevier Science Ltd.
