Earth's magnetic field is generated by fluid motions in the outer core. This geodynamo has
operated for over 3.4 billion years. However, the mechanism that has sustained the …

Because of gravitational interactions with their companions, the rotational dynamics of
planets and stars involve periodic perturbations of their shape, the direction of their …

Precession of planets or moons affects internal liquid layers by driving flows, instabilities and
possibly dynamos. The energy dissipated by these phenomena can influence orbital …

We perform one of the first studies into the non-linear evolution of tidally excited inertial
waves in a uniformly rotating fluid body, exploring a simplified model of the fluid envelope of …

Many planetary bodies undergo forced longitudinal librations [Williams, JG, Boggs, DH,
Yoder, CF, Ratcliff, JT, Dickey, JO, 2001. Lunar rotational dissipation in solid body and …

We report on axisymmetric numerical simulations of rapidly rotating spherical shells in which
the axial rotation rate of the outer shell is modulated in time. This allows us to model …

We describe a new phenomenon of zonal wind generation by tidal forcing. Following a
recent theoretical and numerical analysis [A. Tilgner, Phys. Rev. Lett. 99, 194501 (2007) …

We study by direct numerical simulation the motion of incompressible fluid contained in an
ellipsoid of revolution with ellipticity 0.1 or less which rotates about its axis of symmetry and …

The Poincaré flow (also known as the tilt-over mode) in a precessing cavity filled with water
is investigated experimentally. Assuming that the flow is mainly a solid-body rotation, we …
