High-fidelity simulation of pebble beds: Toward an improved understanding of the wall channeling effect

David Reger, Elia Merzari, Saya Lee +2

Wall channeling is a phenomena of interest for Pebble Bed Reactors (PBRs) where flow is diverted into high-porosity regions near the wall. This diversion of flow can have a signifi…
