Dispersed Flow Film Boiling is the heat transfe regime that occurs at high void fractions in a heated channel. Dispersed flow consists of small liquid droplets entrained in a flowing vapor. This flow regime can occur in cryogenic equipment, in steam generators, and during nuclear reactor loss of coolant accidents. The post-CHF wall temperature can be predicted from empirical correlation or from theoretical models. The models can be divided into two groups: equilibrium and non-equilibrium. The comparison of the calculation results for the wall temperature and heat transfer coefficient with using of different models and computer code KORSAR is represented in this work for the Bennett tube experimental data.
