Two-phase flow regimes during the rewetting and refilling of hot horizontal tubes

The development of accurate mechanistic models for the refilling and rewetting of hot horizontal tubes or rod bundles requires knowledge of the relative phase distribution (ie, flow regimes) encountered during such processes. Characterization of the relative phase distribution is essential in evaluating the interfacial transport of mass, energy, and momentum and hence is important in the development of mathematical models of the refilling and …
