摘要
Nucleate boiling from the restricted geometry between two cylinders in line contact is studied. The pool boiling experiment is conducted using water and two small-diameter tubes brought together through either twisting or tying. It is found that nucleate boiling is significantly enhanced in the restricted regions between the two tubes, particularly in those regions with openings facing upward. This enhancement is due to a favorable thermal environment in terms of the liquid temperature profile inside the restricted geometry. This phenomenon is explained based on the well accepted nucleate boiling theory. The difference among data of different tube orientations is also discussed.
