Abstract
Two-phase flow is present in a wide range of industrial applications, such as solar power, nuclear energy, refrigeration, oil transport pipeline and raw gas transmission. The modelling of such conditions is pivotal to optimal design and operation of two-phase systems. The basic models (homogeneous and separated flow) disagree when the flow pattern is complex, such as annular flow. Thus, the main purpose of this review analysis is to compare experimental results from the open literature to those predicted by models and the pattern-based one, to understand whenever each model should be used and its limitations. The models were implemented in Python and can predict both pressure drop gradient and total pressure loss within the duct length.
