Good Agreement

The influence on cylinder head temperatures of parameters such as cylinder head material, coolant composition, pressure, temperature and velocity was investigated. Each of these parameters was systematically varied and its influence on combustion chamber wall temperature measured. Good agreement is shown between the measured values and corresponding predictions from a heat transfer model incorporating forced-convective, sub-cooled, nucleate boiling. The results suggest that nucleate boiling can play an important role in the transfer of heat from cylinder head to coolant.

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.
