Boiling Heat Transfer on the Outside of A Miniature Diameter Compact Tube Bundle

The advancement of process intensification has necessitated the establishment of an appropriate approach into the boiling outside tubes. This paper present knowledge on the boiling heat transfer outside small diameter tubes and bundles and elucidates the effect of diameter in a compact tube bundle. It is shown that the effect of tube clearance between the tubes restrict the movement of bubbles up the bundle. The confinement number Co is used to investigate the boiling heat transfer inside a tube bundle and it is shown the correlations developed for boiling inside micro channels is appropriate for analysis for compact tube bundles.
