Hydrodynamics of gas-liquid slug flow along vertical pipes in laminar regime- E...
T. S. Mayor; A. M. F. R. Pinto; J. B. L. M. CamposAn experimental and simulation study on free-bubbling vertical slug flow in the laminar regime was developed. A non-intrusive image analysis technique and a developed simulation code (SFS, slug flow simulator) were used for the purpose. A single correlation was obtained for the prediction of the bubble velocity as a function of the length of the liquid slug ahead of the bubble. Strong bubble interaction was fou...

T. S. Mayor; A. M. F. R. Pinto; J. B. L. M. CamposAn image analysis technique for the study of continuous co-current gas–liquid slug flow, in vertical columns, is reported. The technique comprises the automatic analysis of a sequence of video frames with the purpose of object (bubbles) tracking and characterization (dimension, velocity, distance). Its applicability to continuous slug flow conditions (even for very large number of bubbles) and the high ac...
