Abstract

Non-invasive tomographic imaging techniques are appropriate tools for the study of two-phase flow in nuclear thermal hydraulic experiments. Ultrafast X-ray tomography developed at Helmholtz-Zentrum Dresden-Rossendorf can scan two-phase flows both fast and with good spatial resolution. In this paper we introduce the tomography scanner system ROFEX and discuss its application to the study of two-phase flow in pipes – a benchmark problem for two-fluid CFD code development.

Keywords: two-phase flow; ultrafast X-ray tomography; gas holdup measurement; image processing; bubble size measurement; CFD code validation
