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 ...
