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 …

The generation of a magnetic field in an electrically conducting fluid generally involves the
complicated nonlinear interaction of flow turbulence, rotation and field. This dynamo process …

We numerically study precession driven flows in a cylindrical container whose nutation
angle varies between 60 and 90 degrees for prograde and retrograde precession. For …

Precession has been proposed as an alternative power source for planetary dynamos.
Previous hydrodynamic simulations suggested that precession can generate very complex …

Magnetic fields of planets, stars and galaxies are generated by self-excitation in moving
electrically conducting fluids. Once produced, magnetic fields can play an active role in …

In this paper, we present a numerical approach to solve the Navier–Stokes equations for
arbitrary vessel geometries by combining a Fourier-spectral method with a direct-forcing …

The fluid flow in a precessing cylinder is investigated numerically with focus on the Ekman
boundary layers in the strongly forced regime. Not surprisingly, in that regime, we find …

The transition to turbulence in a precessing cylindrical vessel is experimentally investigated.
Our measurements are performed for a nearly resonant configuration with an initially laminar …

Precession driven flows are of great interest for both, industrial and geophysical
applications. While cylindrical, spherical and spheroidal geometries have been investigated …

We investigate with numerical simulations the dynamo properties of liquid flows in
precessing cubes. There are some similarities with the flow in precessing spheres …
