文摘

New experimental data for fluid dynamics and turbulence in bubble columns are presented. The data feature large spatial and temporal resolution and high accuracy for a comprehensive set of observables. A model validated previously for a range of different conditions is used to simulate the experiments with good agreement. This highlights the trustworthyness of the model for predictive applications.
