International audience; In a previous paper, Oruba et al. (J. Fluid Mech., vol. 818, 2017, pp. 205-240) considered the 'primary' quasi-steady geostrophic (QG) motion of a constant density fluid of viscosity ⌫ that occurs during linear spin-down in

On the equatorial Ekman layer

Publikováno v: Journal of Fluid Mechanics. 803:395-435
The steady incompressible viscous flow in the wide gap between spheres rotating rapidly about a common axis at slightly different rates (small Rossby number) has a long and celebrated history. The problem is relevant to the dynamics of geophysical an

Frequency staircases in narrow-gap spherical Couette flow
Autor: Andrew M. Soward, Andrew P. Bassom
Publikováno v: Geophysical & Astrophysical Fluid Dynamics. 110:166-197
Recent studies of plane parallel flows have emphasised the importance of finite-amplitude self-sustaining processes for the existence of alternative non-trivial solutions. The idea behind these mechanisms is that the motion is composed of distinct st

Eulerian and Lagrangian means in rotating, magnetohydrodynamic flows II. Braginsky’s nearly axisymmetric dynamo
Autor: Andrew M. Soward, Paul H. Roberts
Publikováno v: Geophysical & Astrophysical Fluid Dynamics. 108:269-322
The Hybrid Euler–Lagrange (HEL) approach has been usefully applied to weakly dissipative systems characterised by waves riding on mean flow. Soward (Phil. Trans. R. Soc. Lond. A 1972, 272, 431) showed how the HEL-formulation could elucidate remarka

An asymptotic solution of a kinematic -dynamo with meridional circulation
Autor: Andrew M. Soward, Dmitry Sokoloff, Andrew P. Bassom, K. Kuzanyan
Publikováno v: Geophysical & Astrophysical Fluid Dynamics. 107:667-714
Asymptotic methods are used to study a one-dimensional kinematic -Parker dynamo wave model in the limit when the strength of the -sources, as measured by the dynamo number , is large. The model includes the influence of meridional circulation with a

Spin-down in a rapidly rotating cylinder container with mixed rigid and stress-free boundary conditions

Journal of Fluid Mechanics, Cambridge University Press (CUP), 2017, 818, pp.205-240. ⟨10.1017/jfm.2017.134⟩
A comprehensive study of the classical linear spin-down of a constant density viscous fluid (kinematic viscosity \nu) rotating rapidly (angular velocity \Omega) inside an axisymmetric cylindrical container (radius L, height H) with rigid boundaries,

A Boussinesq fluid of kinematic velocity$\nu $and thermal diffusivity$\kappa $is confined within a rapidly rotating shell with inner and outer sphere boundary radii${ r}_{i}^{\ensuremath{\ast} } $and${ r}_{o}^{\ensuremath{\ast} } $, respectively. The

The hybrid Euler–Lagrange procedure using an extension of Moffatt's method
Autor: Paul H. Roberts, Andrew M. Soward
Publikováno v: Journal of Fluid Mechanics. 661:45-72
The hybrid Euler–Lagrange (HEL) description of fluid mechanics, pioneered largely by Andrews & McIntyre (J. Fluid Mech., vol. 89, 1978, pp. 609–646), has had to face the fact, in common with all Lagrangian descriptions of fluid motion, that the v
