Abstract
Results of experimental
studies on dynamics of explosive boiling and third heat transfer crisis under
the conditions of liquid subcooling are presented for the vertical
arrangement of the heat-transfer surface. Acetone was used in experiments at
the pressure in the working volume from 20 to 46 kPa and subcooling from 0 to
20 K. The studied processes were recorded. Data on the velocity of
evaporation front propagation at liquid subcooling were obtained. These data
are compared with the results of calculations according to the models available
in the literature. The effect of liquid subcooling on the regions of regime
parameters corresponding to explosive boiling and third heat transfer crisis is
studied.
