Abstract: |
A large number of pipelines in the petroleum industry simultaneously transport gas and liquid. The transient behavior
of multiphase flow is frequently encountered in these pipelines. A common example is severe slugging that can occur
in multiphase flow systems where a pipeline segment with a downward or even horizontal inclination is followed by
a riser segment with an upward inclination. Transient flow conditions associated with severe slugging are relatively
slow. Therefore, a transient drift flux model consisting of one momentum balance equation might suffice to express
the dynamics of severe slugging. We present a transient drift flux model to simulate severe slugging phenomenon in
pipeline-riser systems. The present model contains recently published correlations by Shi et al. (2005) for the drift
flux slip model which cover the complete range of flow conditions without introducing any discontinuities in the
calculated flow parameters. Thus, the transient simulations are converging rapidly and efficiently without applying
any form of smoothing. The present model is tested against experimental data for severe slugging showing a better
performance than previously published models. |

General Note: |
The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows |
