LIF experiments

For the experiments with CO₂, de-ionized water and water-glycerol mixtures with and without surfactant were used as liquid phase.

Physical properties of the mixtures used in the experiments:

The CO₂ bubbles were generated at 5, 7.5 and 10 l/h air equivalent gas flow rates.


For a better spatial resolution, the bubble column has been divided into several measurement sections:
