Data underlying the examination of ventilated cavities in the wake of a two-dimensional bluff body

These files contain characteristics of ventilated cavities formed in the wake of a two-dimensional wedge at different flow conditions, i.e. flow inertia, gas ventilation rate and ventilation strategies. The main aim of this work was to examine the closure region of the cavities and how it influences gas ejection rates, geometry and gas distribution in the cavity. The void (gas) fraction fields of ventilated cavities are obtained using X-ray densitometry. The full details of the study can be found in the underlying manuscript. This dataset will help researchers for the validation of their numerical models aimed at simulating complex bubbly flows.
