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

In this work the authors draw upon their expertise in geophysical and astrophysical MHD to
explore the motion of electrically conducting fluids, the so-called dynamo effect, and …

Flow between concentric spheres of radius ratio η= ri/ro= 0.35 is studied in a 3 m diameter
experiment. We have measured the torques required to maintain constant boundary speeds …

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 …

Laboratory experiments using liquid metals and nonmetallic liquids reveal a rich set of
dynamical processes active in Earth's core and in the cores of other terrestrial planets …

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 …

Spherical Couette flow (flow between concentric rotating spheres) is one of flows under
consideration for the laboratory magnetic dynamos. Recent experiments have shown that …

Several teams have reported peculiar frequency spectra for flows in a spherical shell. To
address their origin, we perform numerical simulations of the spherical Couette flow in a …

The spherical Couette system, consisting of a viscous fluid between two differentially rotating
concentric spheres, is studied using numerical simulations and compared with experiments …

Sodium has unusual fire hazards, including autoignition when heated in air or exposed to
liquid water. Owing to limitations of existing suppression agents for sodium pool fires …
