ABSTRACT=Post-dryout heat transfer is an important thermal-hydraulic phenomenon happening in the loss of
coolant accident (LOCA) of water-cooled nuclear reactors and the off-design conditions of water
cooled ceramic breeder (WCCB) blanket in fusion reactors. It is necessary to research the flow
and heat transfer mechanisms of Post-dryout. To economically and comprehensively study on the
post-dryout heat transfer characteristics, this work conducted fluid-to-fluid modeling research on
the water and R-134a databanks through using Buckingham dimensional analysis methodology.
In addition, a new interpolation method was developed and verified to make the scaling between
two databanks possible. Finally, a scaling method of post-dryout heat transfer was proposed and
assessed by experimental data. Results showed that the obtained scaling method is reliable in
certain conditions.
