Nucleate Pool Boiling of R-114/Oil Mixtures in a Small Enhanced Tube Bundle

Abstract

Heat transfer tests were carried out using a small tube bundle of Turbo-B tubes in a pool of different R-114/oil mixtures. By accurately instrumenting five tubes within the bundle, both the convective and nucleate boiling regions were studied in detail, with emphasis on the 'bundle effect' (ie. the effect of the lower tubes in operation on the upper tubes within the bundle). In addition, the influence of increased amounts of oil on the tube bundle was studied to see how this affected the overall heat transfer and in particular, the shape of the hysteresis loop.
