Pipelines are used in a huge range of industrial processes involving fluids, and the ability to accurately predict properties of the flow through a pipe is of fundamental engineering importance. Armed with parallel MPI, Arnoldi and Newton--Krylov solvers, the Openpipeflow code can be used in a range of settings, from large-scale simulation of highly turbulent flow, to the detailed analysis of nonlinear invariant solutions (equilibria and periodic orbits) and their influence on the dynamics of the flow.

  1. Laminar gaps mirror turbulent puffs in pipe flow

    physics.flu-dyn 2026-08 conditional novelty 6.0 of 10

    Laminar gaps ('anti-puffs') in turbulent pipe flow at Re=2400-2550 are stabilized by self-tuning front speeds and close with exponentially distributed lifetimes, implying a sharp onset of homogeneous turbulence near Re≈2900.
