... A mechanistic model that predicts the separation of oil-water dispersed horizontal pipe flows was investigated. Different droplet diameter averages were implemented in the model and the accuracy of the resulting predictions was assessed by comparing each case against experimental data...

... ABSTRACT This paper reports on an experiment aimed at obtaining detailed velocity fields in a wavy liquid layer in stratified air/water pipe flow. By combining Particle Image Velocimetry (PIV) with an interface detection technique, the velocity field is resolved from the pipe wall...

... the formation of new slugs during and after their passage. As a result, the frequency of slug formation downstream the pipe is reduced. A probabilistic model is provided by making use of integral scales of turbulence in pipe flow and probabilistic effects of the properties of slug formation along the pipe...

.../Karman pipe flow friction laws, in which the two-phase effect is contained in a flow-dependent effective diameter. Thus, pipe flow friction formulas, ideally suited for 1-D computer models, are obtained from the channel flow expressions by use of a hydraulic similarity transformation of the effective...
