Two-fluid modelling of phase redistribution by obstructions

It is well known that obstructions in two-fluid flow act as mixers, homogenizing the flow towards a more uniform phase distribution, and also causing a significant reduction in relative velocity. Following a recently published study in which a two-dimensional two-fluid computer program was used to demonstrate that these effects could be modelled in concept, this paper extends the analysis to three dimensions and compares results to those obtained in a recent experiment.
