An experimental study of a falling liquid film in a vertical pipe (2017)
Conference Proceeding
Hasan, A., Azzopardi, B., Hewakandamby, B., Mohammed, S. K., & AlAufi, Y. (2017). An experimental study of a falling liquid film in a vertical pipe.

The majority of the experimental and theoretical studies in literature on the falling liquid film focus on either small diameter pipes or flat plates. Almost, all these studies provide time series data of the film thickness at a single point on the p... Read More about An experimental study of a falling liquid film in a vertical pipe.

Simulation and static measurement of the gas volume fraction in a separated flow model using a conductance multiphase Venturi meter (CMVM) (2008)
Conference Proceeding
Hasan, A., & Lucas, G. (2008). Simulation and static measurement of the gas volume fraction in a separated flow model using a conductance multiphase Venturi meter (CMVM). In Proceedings of Computing and Engineering Annual Researchers' Conference 2008: CEARC’08 (69-74)

The assumption of equal mixture densities at the inlet and the throat of the Venturi is only valid in a homogenous flow. This assumption is no longer valid for a separated flow and therefore, the measurement of the gas volume fraction at the throat m...

Modeling of a homogenous gas-water two phase flow through a Venturi and vertical pipe; (A prediction of pressure drop sign change in two phase flow) (2007)
Conference Proceeding
Hasan, A., & Lucas, G. (2007). Modeling of a homogenous gas-water two phase flow through a Venturi and vertical pipe; (A prediction of pressure drop sign change in two phase flow). In Proceedings of Computing and Engineering Annual Researchers' Conference 2007: CEARC’07

In two phase flow, differential pressures technique can be used to measure the volume fraction of the gas phase. In the case where no restriction is available in the pipeline, the differential pressure technique can be used only in vertical or incl...

Experimental characterization of interfacial wave structure of a falling liquid film in a vertical large pipe diameter
Conference Proceeding
Hasan, A., Azzopardi, B., Hewakandamby, B., AlAufi, Y., Watson, N., & Mohammed, S. (2016). Experimental characterization of interfacial wave structure of a falling liquid film in a vertical large pipe diameter.

There is considerable literature on the thicknesses of falling liquid films, much of which is focussed on either flat plates or small diameter pipes. Many studies provide time series data of the film thickness at one or two points on the pipe wall. T...

Modelling and measurement of the gas flow rate in vertical annular gas-water flow using a conductance multiphase Venturi meter
Conference Proceeding
Hasan, A., & Lucas, G. (2009). Modelling and measurement of the gas flow rate in vertical annular gas-water flow using a conductance multiphase Venturi meter.

Separated flow in a Venturi meter is highly complex and the application of a homogenous flow model could not reasonably be expected to lead to highly accurate results. If this is the case, a gas volume fraction measurement technique at the throat mus...
