MODELING 2-PHASE FLOWS USING CFD

Two-phase flows are encountered in a wide range of industrial and natu ral situations. Due to their complexity such flows have been investiga ted only analytically and experimentally. New computing facilities pro vide the flexibility to construct computational models that are easily adapted to a wide variety of physical conditions without constructing a large-scale phototype or expensive rest rigs. But there is an inher ent uncertainty in the numerical predictions due to stability, converg ence and accuracy. The importance of a well-placed mesh is highlighted in the modelling of two-phase flows in horizontal pipelines.
