LIF experiments

For the experiments with air, a mixture of de-ionized water, resazurin, glucose and sodium hydroxide; de-ionized water and water-glycerol mixtures with and without surfactant were used as liquid phase.

Physical properties of the mixtures used in the Shadowgraphy 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:

The PIV and LIF experiments were carried out in the following mixture:
