Hydrodynamics of gas-liquid slug flow along vertical pipes in laminar regime- E...

An 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...

Interaction between Taylor bubbles rising in stagnant non-Newtonian fluids

The interaction between Taylor bubbles rising in stagnant non-Newtonian solutions was studied. Aqueous solutions of carboxymethylcellulose (CMC) and polyacrylamide (PAA) polymers were used to study the effect of different rheological properties: shear viscosity and viscoelasticity. The solutions studied covered a range of Reynolds numbers between 10 and 714, and Deborah numbers up to 14. The study was performed...

An image analysis technique for the study of gas-liquid slug flow along vertica...

An 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...

Separation of solutes with different diffusivities in a hybrid membrane cell co...

A hybrid separation membrane cell comprising semi and fully-permeable membrane sections is employed to fractionate solutions containing a solvent and two solutes, namely BSA and dextran. The separation technique takes advantage of the difference between diffusivities of the solutes. The semi-permeable membranes are permeable to the solvent and impermeable to both solutes and the fully-permeable membranes are pe...
