The paper “Frictional Fluid Dynamics and Plug Formation in Multiphase Millifluidic Flow” (Dumazer_PRL028002) was picked as PRL “Editors’ Suggestion”, and was “Featured in Physics”:
Synopsis: Forming Granular Plugs
See also: News and FYFD
A repeating pattern of granular plugs emerges when a tube filled with water and grains is slowly drained. The moving air-water meniscus bulldozes the grains ahead, and friction eventually causes the grains to jam, forcing the air to penetrate through the accumulated material. Once through to the other side, the air starts to pile up another plug, and the process repeats until the whole tube is clogged full of granular plugs separated by empty gaps.
