摘      要：The practice of stepping a conveying line is not new and there are many examples in industry; however, the details of the flow behaviour at the step have not been extensively studied. Three step geometries were modelled： an ＇abrupt＇ step and two ＇gradual＇ step-up geometries from a pipe bore of 75-100 ram. The flow behaviour of a single plug of material passing through these geometries was investigated using the ＇Eulerian＇ CFD model from Fluent. Solids volume fractions were recorded at 0.01 s time steps at several point locations, and visualised throughout the pipe.
