▪ Abstract Recent developments in the study of buoyancy-driven convection,
magnetoconvection, and convection-driven dynamos in rapidly rotating spherical systems …

Magnetism is one of the most pervasive features of the Universe, with planets, stars and
entire galaxies all having associated magnetic fields. All of these fields are generated by the …

We analyse∼ 50 3-D numerical calculations of hydrodynamic dynamos driven by
convection in a spherical shell. We examine rigid and stress-free boundaries, with Prandtl …

Conduction in solids. 4. Fluids in rotation. 5. Perfect fluids and their application to the theory …

The past few years have seen the emergence of a large number of numerical simulations of
the geodynamo. In parallel, both new and old geomagnetic, archeomagnetic, and …

A linear analysis is used to study the stability of a rapidly rotating, electrically-conducting,
self-gravitating fluid sphere of radius r 0, containing a uniform distribution of heat sources …

The linear and nonlinear stabilities of a horizontal layer of an elasticoviscous fluid, whose
stress-rate-of-strain relations are due to Oldroyd (1958), are studied. In the linear theory it is …
