Abstract

This study has been carried out using Computational Fluid Dynamics (CFD) to investigate the annular
two phase flow behavior that flow pattern has some desirable features for renewable energy system
application. The circumferential distribution of the liquid film in a small diameter horizontal pipe (ID =
8.8mm) is non-uniform owing to gravitational force, where liquid film is thicker at the bottom than that at
the top. In a wavy-annular flow regime, large amplitude waves formed at the gas-liquid interface has
played a significant role to replenish the top liquid film.
