Abstract
Experiments are described on the effect of pressure on the slug/churn flow pattern transition in vertical upwards gas-liquid flow. The experiments wer e conducted with air-water flow in a 32 mm, 12.6 m long tube and the flow r egime transitions were determined using the impedance probe. It was shown t hat the slug/churn transition was well predicted by the model, though this model slightly over-predicted the effect of pressure. (C) 1999 Elsevier Sci ence Ltd. All rights reserved.
