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