Two-Phase Flow Pressure Drop Model for a Shell Side of a Shell of Heat Exchanger

摘要

This paper present a two-phase pressure drop model for a in-line tube bundle for air- water mixtures flowing through an idealised shell and tube, in-line heat exchanger. The model used momentum flux and entrained liquid fraction to predict the acceleration pressure drop. The model predicts the pressure drop well using both accelaration and gravitational pressure drop deduced from data available in open literature. The model is shown to be mass flux dependence.
