With this motivation, Feldmann & Avila (2025) J. Fluid Mech, 1008, R1, carry out long-time numerical simulations of axisymmetric high-Reynolds-number Taylor–Couette flow. They find that the Taylor vortices, using the only degree of freedom that remains available to them, carry out Brownian motion in the axial direction, with a diffusion constant that diverges as the number of rolls is reduced below a critical value.OPENtransition to turbulencePhysics - Fluid Dynamics[NLIN] Nonlinear Sciences [physics]Taylor-Couette flowFluid Dynamics (physics.flu-dyn)FOS: Physical sciences[PHYS.MECA.MEFL] Physics [physics]/Mechanics [physics]/Fluid mechanics [physics.class-ph]publication2506.00621
