Nucleate pool boiling performance of smooth and finned tube bundles in R-113 and R-114/oil mixtures
nucleatepoolboil00ande.pdf (29.18Mb)Abstract
Heat-transfer measurements were made for boiling of
refrigerants and refrigerant/oil mixtures from smooth and
finned tube bundles. The bundles contained 15 heated tubes
arranged in an equilateral triangular pitch of 19.1 mm. The
outside diameter of the smooth tubes (15.8 mm) was equal to
the diameter to the tip of the fins of the finned tubes.
The smooth tube bundle was tested in pure R-113 with varying
surface "histories" as well as with pure R-114 and R-ll4/oil
mixtures. The finned tube bundle was tested in pure R-114
and R-114/oil mixtures. Oil concentrations used were 1, 2,
3, 6, and 10% by mass.
