    <subfield code="a">&lt;p&gt;This data repository contains reconstructed and quantitatively analyzed gas-liquid two-phase distributions obtained from a centrifugal pump mock-up whose geometry is related to a commercially available industrial centrifugal pump. As measurement system the ultrafast electron beam X-ray CT scanner (UFXCT) is applied with a frame rate of 2,500 Hz, single-plane mode and a total scanning interval of 10 seconds. The data repository contains:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;Reconstructed raw data sets (Algebraic Reconstruction Technique from the UFO framework) for different inlet gas fractions (eps0.0xx) at constant 1480 rpm and for both rotating and back-rotated impeller positions, respectively&lt;/li&gt;
	&lt;li&gt;Extracted RPM per CT scan (frame) including its raw data&lt;/li&gt;
	&lt;li&gt;Extracted angular positions of the impeller mock-up per frame&lt;/li&gt;
	&lt;li&gt;Calculated quantitative gas fraction data sets (static impeller position)&lt;/li&gt;
	&lt;li&gt;Time-averaged gas fraction distribution and its corresponding averaged variance&lt;/li&gt;
	&lt;li&gt;Pump and impeller mask data&lt;/li&gt;
	&lt;li&gt;Additional data obtained from the SPS server with a sampling frequency of 1 Hz&lt;/li&gt;
&lt;/ul&gt;</subfield>
