Numerical simulation of core-annular flow in curved pipe

A numerical study, using the volume-of-fluid method (VOF), has been made of core-annular flow in a curved pipe. We investigated two cases: core-annular flow in a 90 bend and in a 180 return bend. Special attention was given to the influence of secondary flows perpendicular to the pipe axis. These secondary flows play an important role in the behaviour of core-annular flow in a curved pipe.MSC program/Mechanical EngineeringProcess and EnergyMechanical, Maritime and Materials Engineerin
