Abstract

A numerical study, using the volume-of-fluid method, has been made of laminar core-annular flow in a 90° bend. To verify the numerical method we first compared our results for a single-phase flow in a 90° bend with numerical results and experimental data given in the literature. The agreement was good. Thereafter a detailed analysis was made of the velocities and pressures occurring in core-annular flow in a 90° bend. Special attention was given to the influence of the secondary flow perpendicular to the pipe axis. This secondary flow plays an important role in the behaviour of core-annular flow in a curved pipe.
