摘要
The characteristics of two-phase flow and heat transfer in an internal thermosyphon boiling device withchannels of different geometrical shapes and dimensions including straight and helical channels have beeninvestigated.The swirl-flow boiling device has more stable performance,higher heat transfer coefficientand higher rate of fouling removal than those of straight flow and has been successfully used in severalkinds of vaporizing equipment,such as reboiler,evaporator and closed thermosyphon.
