Results for the rate of absorption of carbon dioxide gas into a pneumatic (i.e. continuously rising) foam formed from a sodium carbonate–bicarbonate buffer solution stabilised by a polyglycol frother are presented. Previous studies upon the use of ga... Read More about Gas absorption and reaction in a wet pneumatic foam.

Numerical study of Taylor bubbles with adaptive unstructured meshes (2014)
Presentation / Conference Contribution
Hasan, A., Xie, Z., Pavlidis, D., Percival, J., Pain, C., Matar, O., & Azzopardi, B. (2014, November). Numerical study of Taylor bubbles with adaptive unstructured meshes. Presented at 67th Annual Meeting of the APS Division of Fluid Dynamics, San Francisco, USA

The Taylor bubble is a single long bubble which nearly fills the entire cross section of a liquid-filled circular tube. This type of bubble flow regime often occurs in gas-liquid slug flows in many industrial applications, including oil-and-gas produ...

Slugs in a large diameter column with air and high viscosity silicone oil (2014)
Presentation / Conference Contribution
Hasan, A., & Azzopardi, B. (2014, November). Slugs in a large diameter column with air and high viscosity silicone oil. Presented at 67th Annual Meeting of the APS Division of Fluid Dynamics, San Francisco, USA

Very little information is known about the behaviour of high viscous liquids (> 100 Pa.s) in two phase slug flows. Experiments were carried out to study the behaviour of silicone oil (300 Pa.s) in gas bubble column using electrical capacitance tomogr...
