Inverted annular boiling in a stainless-steel tube with steady heat sources

Abstract Simultaneous measurements of wall temperatures and vapor film thicknesses in an inverted annular film boiling are reported. The data correspond to bottom reflooding of a single tube uniformly heated with a steady electric heat source. The raw data are processed to yield the wall heat flux, heat transfer coefficient, quench front velocity, quench front temperature and void fraction, which may serve as a relatively complete comparative base for the development of theoretical models.
