ABSTRACT

A common problem in experimental multiphase flow studies is the tracking of structures in the flow domain. Such may be for example particles, bubbles and waves. Ultrafast electron beam X-ray computed tomography (UFXRCT) is a fast cross-sectional imaging technique, which is applicable to opaque multiphase flows. However, as it is a 2D imaging technique, we can only obtain statistical information about properties of moving structures in the given axial planes so far. To progress towards tracking of structures we now devised a novel approach for dynamic imaging-based structure tracking. For that the tomography scanner follows the structure of interest by controlled positioning basing on real-time image data analysis. This approach is described in the following.
