Models of gas-liquid solubilities
… of the components. Distinction between vapour-liquid equilibria and gas-liquid solubility is rather arbitrary and it seems reasonable to extend these ideas to solubility. The AGAPE model uses a molecular lattice-based mixing rule. By judicious use of computer programs a methodology was created …

Thermodynamic Measurements by Gas-Liquid Chromatography
… the large scale continuous and semi-continuous gas liquid chromatographs (G.L.C.) in operation in this department by using analytical G.L.C. equipment. A commercial dual-channel chromatograph was modified to enable the partition coefficients of various solutes in polymer stationary phases to be …

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.

Characteristics of the High Speed Gas-Liquid Interface
… physical characteristics of high speed gas-liquid interfaces for the cases of subsonic, transonic, and supersonic gas jets submerged underwater and the transient development of an underwater projectile reaching the supercavitating state. These studies are motivated by the need to …

Gas-liquid simulation of an airlift bubble column reactor
… on industries such as bioprocess industries. The gas-liquid of two-phase fluid flow system has been carried out to investigate the hydrodynamics parameter. An Eulerian-Eulerian approach was used to model air as the dispersed phase within a continuous phase of water using the commercial software …

Studies in three phase gas-liquid-solid fluidised systems
… and petroleum operations involving three-phase, gas-liquid-solid fluidisation; such systems are in increasing use. It is believed that this is one of few studies concerned with `true' three-phase, gas-liquid-solid fluidised systems, and that this work will contribute significantly to closing some …

A Gas-Liquid Reactor for High Mass Transfer Rates
The overall reaction rate of an absorbed gaseous reactant in a liquid solution is usually influenced by the combined effect of the reaction kinetics and heat and mass transfer rates. The kinetic study of such reactions requires the thorough understanding of the physical rate processes accompanied …

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 …

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. …
