Multiphase flow analysis using a compact gamma-ray CT system

Bieberle, A.; Härting, H.-U.; Schubert, M.; Hampel, U.

A new compact high-resolution gamma-ray computed tomography measurement system (CompaCT) has been developed for the determination of phase fraction distributions in multiphase flows occurring in technical devices with dense housings and inlets. The obtained data is used to understand fundamental physics behind flow processes and to validate flow simulation codes. The CompaCT contains a 137Cs isotopic source and a gamma-ray detector arc, whose single detectors are thermally stabilized. The entire analogue and digital signal processing are implemented within the detector arc. As examples, performance studies of qualitative and quantitative phase structure determination were accomplished in a steel rod bundle and a fixed bed reactor assembly.
