Bubbling


The rising motion of multiple gas bubbles in a liquid can be quite complex because of interactions between the bubbles. In large bubbling columns, excessive coalescences can have adverse effects on gas-liquid contacting, and understanding bubble interactions and dynamics can have profound implications on many industrial processes and perhaps, in a fundamental way, lead to a deeper understanding of fluidized-bed reactors.

The CRG has studied the dynamics of a single-nozzle bubble column since 1992. Major work has explored the period-doubling route to chaos and the spatio-temporal nature of bubble interactions, and currently is focused on the application of chaos-control techniques.

We have compiled a "Bibliography of chaos and bubbling" to assist in further research.

Primary contacts for this research area are: C.S. Daw and D.D. Bruns.
