    <dct:description>&lt;p&gt;For the investigation of bubbly two-phase flow,&amp;nbsp;which should serve as a future benchmark experiment for CFD code validation, an experimental study has been conducted at the&amp;nbsp;&lt;strong&gt;T&lt;/strong&gt;ransient Tw&lt;strong&gt;o-P&lt;/strong&gt;hase&amp;nbsp;&lt;strong&gt;Flow&lt;/strong&gt;&amp;nbsp;(TOPFLOW) facility at Helmholtz-Zentrum Dresden &amp;ndash; Rossendorf (HZDR) using&amp;nbsp;ultrafast electron beam X-ray tomography (UFXRAY). In this study, flow constrictions were installed into a pipe&amp;nbsp;to create a generic three-dimensional flow field&amp;nbsp;as an advanced test case for CFD codes. UFXRAY provide valueable data of the gas phase dynamics with high temporal and spatial resolution.&lt;/p&gt; &lt;p&gt;The provided data set contains the entire results of the experimental series L30&amp;nbsp;that uses a&amp;nbsp;&lt;strong&gt;semi-circular&lt;/strong&gt;&amp;nbsp;flow constriction with a blockage ratio of 0.5.&amp;nbsp;&lt;/p&gt; &lt;p&gt;An additional info.txt file provides all required information (e.g. nomenclature or&amp;nbsp;binary file structure) and is, thus, necessary for interpretation of the experimental data.&lt;/p&gt;</dct:description>
