| Abstract: | On the basis ofthe classification and definitions of two regions of pressure drop oscillation in ourprevious work, the transient and time-averaged heat transfer characteristics ofsteam-water two-phase flow during the second regional pressure drop oscillation wereexperimentally studied in a closed circulation system with a helical coiled tube boilingchannel. New non-dimensional parameters and criterion for characterizing the effects ofsecond regional pressure drop oscillation on transient and time-averaged heat transfercoefficient were proposed. |
