Experimental study of interfacial structure of a falling liquid film in a vertical pipe (2015)
Presentation / Conference
Hasan, A., Azzopardi, B., & Hewakandamby, B. (2015, November). Experimental study of interfacial structure of a falling liquid film in a vertical pipe. Presented at American Physical Society-Fluid Dynamics Fall Meeting

Many studies in the literature provide time series data of the film thickness at one or two points on the pipe wall. Most of these studies focussed on either flat plates or small diameter pipes. The main aim of this paper is to study the characterist... Read More about Experimental study of interfacial structure of a falling liquid film in a vertical pipe.

Taylor bubbles at high viscosity ratios: experiments and numerical simulations (2015)
Presentation / Conference
Hasan, A., Hewakandamby, B., Azzopardi, B., Xie, Z., Pain, C., & Matar, O. (2015, November). Taylor bubbles at high viscosity ratios: experiments and numerical simulations. Presented at 68th Annual Meeting of the APS Division of Fluid Dynamics, USA, Boston

The Taylor bubble is a single long bubble which nearly fills the entire cross section of a liquid-filled circular tube, often occurring in gas-liquid slug flows in many industrial applications, particularly oil and gas production. The objective of th... Read More about Taylor bubbles at high viscosity ratios: experiments and numerical simulations.

Slugs in a large diameter column with air and high viscosity silicone oil (2014)
Presentation / Conference
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...

Numerical study of Taylor bubbles with adaptive unstructured meshes (2014)
Presentation / Conference
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...
