Characterization of flow regimes in the post-dryout region

OSTI ID:7083734
A visual study of film boiling using photographic and high speed motion-picture methods was carried out to determine the flow regime transition criteria in the post-CHF region. An idealized inverted annular flow was obtained by introducing a liquid jet of Freon 113 through a nozzle, precisely centered with respect to the internal diameter of the test section, with an annual gas flow. The respective ranges for liquid and gas exit velocities were 0.05-0.5 and 0.03-8.2 m/s. Nitrogen and helium were used in the study.
