Magnetic field generation and evolution in celestial bodies—the subject matter of the theory
of the dynamo—held Ya B Zeldovich's interest for years. Over the time since then, the study …

Understanding fluid flows in planetary cores and subsurface oceans, as well as their
signatures in available observational data (gravity, magnetism, rotation, etc.), is a …

Context. Main sequence stars with a convective core are predicted to stochastically excite
internal gravity waves (IGWs), which effectively transport angular momentum throughout the …

We investigate the properties of small-amplitude inertial waves propagating in a differentially
rotating incompressible fluid contained in a spherical shell. For cylindrical and shellular …

We present new experimental results from the University of Maryland Three Meter
Geodynamo experiment. We drive a fully turbulent flow in water and also in sodium at …

Recent decades have seen enormous progress in the experimental investigation of
fundamental processes that are relevant to geophysical and astrophysical fluid dynamics …

Identification and extraction of vortical structures and of waves in a disorganised flow is a
mayor challenge in the study of turbulence. We present a study of the spatio-temporal …

Experimental survey of linear and nonlinear inertial waves and wave instabilities in a spherical
shell Page 1 J. Fluid Mech. (2016), vol. 789, pp. 589–616. c Cambridge University Press 2016 …

The spherical Couette system is a spherical shell filled with a viscous fluid. Flows are driven
by the differential rotation between the inner and the outer boundary that rotate with [formula …

We begin with an experimental investigation of the flow induced in a rotating spherical shell.
The shell globally rotates with angular velocity Ω. A further periodic oscillation with angular …
