Large Amplitude Waves In
A Slug Tracking Scheme
Author(s)
A. De Leebeeck & O. J. Nydal
Abstract
Large amplitude roll waves are incorporated into a previously developed slug
tracking scheme for two phase gas-liquid pipe flow. The applicability of the
tracking scheme to large amplitude waves is demonstrated with a simplified
model for the waves. The waves are modelled analogous to slugs on a moving
grid with corresponding wave velocities and a pressure variation determined
using an orifice type relation. Slugs and waves in the tracking scheme are
separated by regions of stratified flow, which are modelled on a stationary grid
using the two-fluid model. The computational scheme is described, compared to
experimental data on roll waves, and some wave dynamics such as waves
developing to slugs and slugs decaying to waves are demonstrated.
Keywords: roll waves, tracking, two phase pipe flow, modelling.
