Folding morphologies of miscible viscous threads. Liquids are indexed symmetrically from the center of the channel outwards. Volume flow rates are in ; viscosities are in cP. (a) Single folding (strong diffusion): , , , . Striations of high viscosity liquid from the folds are convected outside the folding envelope. (b) Single folding (weak diffusion): , , , . (c) Subfolding of a thread (period doubling): , , , . (d) Heterogeneous (chaotic) deposition of a thread into a pile: , , , . (e) Multiple folding: , , , , . The threads fold initially in phase. (f) Viscous swirls: , , , , . (g)–(i) Viscous dendrites: , , , , . (g) , (h) , (i) . The least viscous liquid in the center inhibits complete folding, thereby creating dendritic fingering and swirling morphologies (enhanced online).
