We present experimental results for bubble columns with different diameters in both the homogenous and heterogeneous regime. We cover two different time-dependent situations. First, the startup of the bubble column is considered. This unsteady regime consists on injecting a fixed gas flowrate starting from zero. The time that bubbles require to reach the free surface and the duration of the unsteady regime are then analyzed. Later, we focus on the fluctuations of several quantities (void fraction, bubble velocity…) within stable operating conditions. Our results show that even within steady gas injection conditions, all studied parameters present significant fluctuations.
