Inferring liquid chaotic dynamics in bubble columns

Experiments carried out to study the liquid displacements in bubble columns via the computer automated radioactive particle tracking technique are analyzed by means of Lagrangian and qualitative dynamics tools. The Lagrangian approach yields the detailed motion sequences of the tracer as entrained b...
