This dataset combines multiple measurements form air-water horizontal annular flow experiments in a pipe (case A) and a pipe with circular orifice with \({d^2 / D^2} = 0.6\) (case B). Measurements where taken at superficial Reynolds numbers of Re=25000 for the gas phase and Re =4090 for the liquid phase. The following data are included for each case:
- linear pressure drop between two points (case A), four points (case B) measured with split-range differential pressure transducers at 5Hz
- time-averaged local liquid volume fraction distribution in cylindrical and Cartesian coordinates reconstructed from X-ray microtomography projections
- reconstructed pipe axis coordinates and pipe radius
- Python code to calculate secondary validation parameters (e.g. film thickness distribution) from primary data
The detailed 3D data is intended for validation of computational fluid dynamics codes based on phase-averaged variables such as the Euler-Euler approach.
