Hydrodynamics and mass transfer in bubble column: Influence of liquid phase surface tension [PDF]
, 2007 According to literature, few experiments are performed in organic solvents which are mostly used in commercial gas–liquid reactors. However, it is commonly accepted that data obtained in aqueous solution allow to predict the surface tension effects, and ...

Characteristics of Bubbles and Gas Holdup In A Two-Phase Column For Different Liquid Phases [PDF]
Engineering and Technology Journal, 2007 Experimental study of gas holdup (Eg), bubble diameter (dvs) interfacial area(a) m-1, small bubble rise velocity (Ubs), and bubble rise velocity (Ubr) in (0.1mi.d) and (1.5m) high column operated at ambient temperature and pressureconditions.

Effect Of Solid Catalyst On Bubble Rise Velocity And Gas- Drift Flux In Three-Phase-Columns [PDF]
Engineering and Technology Journal, 2007 The bubble rise velocity and drift flux were measured in 0.051 m i.d glass column with ethanol as the liquid phase, cobalt catalyst as the solid phase in concentration varying from (1.0 to 0.4) vol % in three phase column.

Polydispersity Effects in the Dynamics and Stability of Bubbling Flows
, 2005 The occurrence of swarms of small bubbles in a variety of industrial systems enhances their performance. However, the effects that size polydispersity may produce on the stability of kinematic waves, the gain factor, mean bubble velocity, kinematic and ...
