Nonlinear Interfacial Waves in Inviscid Gas-Liquid Flows
… the interfacial waves that exist in stratified gas-liquid flows. The motivation is the central role that interfacial waves are believed to play in flow regime transitions as well as their effect in critical design parameters.

Slug Formation and Frequency of Slugging in Gas-Liquid Flows
When a slug forms, the liquid level in a large length of pipe drops as the slug propagates downstream. Thus two time scales enter the slug frequency analysis: one characterizing wave evolution and one involving liquid buildup. When the Froude number of the stratified flow in a horizontal pipe at …

Experimental Investigations of Internal Air-water Flows
… and data analysis techniques to the study of gas-liquid pipe flows, with a focus on conditions occurring in header-feeder systems of nuclear reactors under different accident scenarios. Novel experimental techniques have been proposed for the identification of the flow regime and measurement …

Microfluidic synthesis of colloidal nanomaterials
… with tunable sizes. Microscale segmented gas-liquid flows overcome the large axial dispersion effects associated with single-phase laminar flows. Microchannel devices that yielded uniform, stable gas-liquid segmented flows over three orders of magnitude in flow velocity were first …

Assessment strategies for mixing in very viscous gas-liquid two-phase flows
… In the reactor, combustion products of natural gas combustion are bubbled through the three phase recirculating tank reactor. The turbulence generated by the rising bubble column causes rapid heating and mixing of the charge resulting in fast melting and homogeneous composition of the product. …

Mechanistic study of slug formation and evolution in high-viscosity-liquid/High-density-gas multiphase flows in channels/pipes
… operation of pipelines to transport heavy-oil/gas flows have raised new challenges associated with remarkably different flow regime transitions compared to conventional low-viscosity-oil/low-density-gas flows. Many traditional flow regime models for these oil/gas flows result in O(1) prediction …

Characterisation and simulation of bidirectional multiphase flow in tubes
… flow reversal phenomenon results in liquid accumulation, causes significant increase in pressure drop and therefore, the pumping power. In pipelines, this poses significant problem due to the presence of slug to churn, especially in producing gas wells. To understand the bidirectional …

Mass transfer and particle dissolution in liquid-gas and solid-liquid flows: Application to hydrogen production processes.
… water, bubble flow and vapour transfer into the gas phase occur during phase transition. This undesirable vapour transfer requires the use of more energy input to compensate for the evaporation heat requirement as well as for subsequent gas purification in the downstream unit. This work examines …

Computations of bubble dynamics with heat transfer
Gas-liquid flows with heat transfer play an important role in many natural and industrial processes such as combustion, petroleum refining. In particular, the heat transfer enhancement caused by air bubble motion is of practical interest in many industrial applications ranging from boiling solar …
