    <subfield code="a">&lt;p&gt;This dataset combines multiple measurements form&amp;nbsp;air-water horizontal annular flow experiments in a&amp;nbsp;pipe (case A) and a pipe with circular orifice with&amp;nbsp;&lt;span class="math-tex"&gt;\({d^2 / D^2} = 0.6\)&lt;/span&gt;&amp;nbsp;&amp;nbsp;(case B). Measurements where taken at superficial Reynolds numbers of Re=25000 for the gas phase and Re =4090&amp;nbsp;for the liquid phase.&amp;nbsp;The following data are included for each case:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;linear pressure drop between&amp;nbsp;two points (case A), four points (case B) measured with split-range differential pressure transducers at 5Hz&lt;/li&gt;
	&lt;li&gt;time-averaged local liquid volume fraction distribution in cylindrical and Cartesian coordinates reconstructed from X-ray microtomography projections&lt;/li&gt;
	&lt;li&gt;reconstructed pipe axis coordinates and pipe radius&lt;/li&gt;
	&lt;li&gt;Python code to calculate secondary validation parameters (e.g. film thickness distribution) from primary data&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The detailed 3D data is intended for validation of computational fluid dynamics codes based on phase-averaged variables such as the Euler-Euler approach.&lt;/p&gt;</subfield>
