This archive contains the processed X-ray data of the measurement campaign "Investigation of flow morphology and heat transfer in an inclined tube", which was conducted between June 2020 and June 2021 at the thermal hydraulic test facility COSMEA (COndenSation test rig for flow Morphology and hEAt transfer studies) at Helmholtz-Zentrum Dresden - Rossendorf (HZDR). The flow morphology of high-pressure (up to 65 bar) steam condensation in a slightly inclined tube at low inlet steam qualities (down to 2.8%) were are studied. Both X-ray computed tomography as well as X-ray radioscopy have been applied. The results include images of the local condensate distribution in selected cross-sections of the condenser tube as well as time resolved projections of the condensate distribution.
