 Notes Abstract: The one-group and two-group interfacial area transport equations (IATE) and their closure relations have been established based on the fluid particle number density transport equation. These equations can be used to solve gas-dispersed two-phase flows, such as bubbly, cap-bubbly, slug, and churn-turbulent flows. However, they cannot handle annular flows because the particle number density transport equation cannot describe the transport phenomena occurring at a film/gas interface. In regard to this, an approach based on a local instant formulation of interfacial area concentration and its transport equation is established for the development of IATE in annular flows. The mathematical expressions of interfacial area concentration, interfacial area transport velocity, source/sink terms and multiple-group IATE are derived. Application of this formulation to annular flows is presented for three groups, namely, liquid droplets, bubbles, and a film/gas interface. The relation between the local instant approach and the particle number density transport approach and the development of IATE over the entire spectrum of two-phase flow regimes is also briefly discussed in the paper. 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
