| Abstract: | Helical baffle heat exchanger is a kind of high efficient and energy-saving heat-echanger, so research on the heat transfer and flow resistance characteristic of air helical flow outside upright tube is of research sense on improving the heat-transfer efficience of helical baffle heat exchanger and high efficiency and energy-saving patten of helical baffle heat exchanger, such as petal-shape, finned-shape heat exchanger and so on. Aimed at it, the experimental process of air helical flow outside of upright tube was introduced, the according experimental method and procedure was explained and the data processing method on heat-transfer coefficiency and flow resisitence was discribed. It offered experimental guidance and reference to this kind of experiment. |
