“…Among phenomenological approaches, liquid film flow with different settings in annular and other annular related streams; as dryout and post-dryout, droplet entrainment, evaporation and droplet deposition is considered [3,4]. After the flowing proportion of the liquid film or related size of itregarding thickness-declines under a critical value or to zero, phenomenological methods assume that the dryout arises [5][6][7][8][9]. During the estimation phase of dryout, there are numerous diverse systems applied.…”

A theoretical post-dryout heat transfer model is developed for two-phase dispersed flow, one-dimensional vertical pipe in a post-CHF regime. Because of the presence of average droplet diameter lower bound in a two-phase sparse flow. Droplet diameter is also calculated. Obtained results are compared with experimental values. Experimental data is used two-phase flow steam-water in VVER-1200, reactor coolant system, reactor operating pressure is 16.2 MPa. On heater rod surface, dryout was detected as a result of jumping increase of the heater rod surface temperature. Results obtained display lower droplet dimensions than the experimentally obtained values.
