A theoretical post-dryout heat transfer model is developed based on one-dimensional two-phase dispersed flow and is applied to calculate the wall temperatures in the post-CHF regime. The model is also applied to reason the existence of a lower bound for average droplet diameter in two-phase dispersed flow. Results obtained using data by Bennett, et al. show lower droplet sizes than the experimentally measured values.
