Ultrafast X-ray computed tomography is an advanced imaging technique for multiphase flows. It has been used with great success studying gas–liquid as well gas–solid Here, we apply this to analyze density-driven particle segregation in a rotating drum exemplary use case analyzing industrial mixing systems. As glass particles are the denser of two granular species be mixed, beam hardening artefacts occur and hamper data analysis. In general distribution arbitrary materials, inverse problem...
The transient mixing dynamics of an initially segregated binary granular system in a half-filled rotating drum are experimentally investigated. consists spherical beads having identical size. density ratio between the two phases is 2.8. With its ability to scan three-dimensional opaque systems with high frequency, ultrafast X-ray computed tomography used capture and steady-state segregation bulk. also compared those at circular end-wall caps, which have been captured camera. results show...
