Abstract

We show that in circular Couette flow (i) for the transition to steady Taylor-vortex flow and (ii) for the transition to time-dependent wavy-vortex flow a space-dependent order parameter obeys a Ginzburg-Landau-type equation. Our measurements allow extrapolation of the critical Reynolds numbers to infinitely long cylinders.

    The annulus between the cylinders is filled with a working fluid; most commonly, as in our case, water is chosen. The apparatus has been used to study hydrodynamic instabilities, pattern formation, turbulence, and was found to have a rich phase diagram with different types of flow structures [1–11]. To get a deep understanding of these phenomena it is crucial to measure the local flow velocity.

    In contrast with their work, we include an O(1) boundary condition that forces the flow strongly. This approach is also distinguished from approaches based on using the Ginzburg–Landau equation for the envelope of the vortex amplitude [20,21]. Indeed, Ahlers et al. [21] obtained quantitative agreement with the experimental measurements of the onset of Taylor vortices, using the Ginzburg–Landau equation with an O(1) inhomogeneous boundary condition, inspired by earlier work of Graham and Domaradzki [22].
