The Unsteady Taylor--Vortex Dynamo is Fast
Liam O'Connor, Daniel Lecoanet, Geoffrey M. Vasil +6
Astrophysical and geophysical fluids commonly generate organized magnetic fields, despite having enormous magnetic Reynolds numbers and abundant small-scale turbulence. F…
Rapidly Rotating Wall-Mode Convection
Geoffrey M. Vasil, Keaton J. Burns, Daniel Lecoanet +3
In the rapidly rotating limit, we derive a balanced set of reduced equations governing the strongly nonlinear development of the convective wall-mode instability in the interior of…
Iterative Methods for Navier--Stokes Inverse Problems
Liam O'Connor, Daniel Lecoanet, Evan H. Anders +5
Even when the partial differential equation underlying a physical process can be evolved forward in time, the retrospective (backward in time) inverse problem often has its own cha…
Convection in a mushy-layer along a heated wall
Samuel Boury, Colin R. Meyer, Geoffrey M. Vasil +1
Motivated by the mushy zones of sea ice, volcanoes, and icy moons of the outer solar system, we perform a theoretical and numerical study of boundary-layer convection along a verti…
Aspect ratio affects iceberg melting
Eric W. Hester, Craig D. McConnochie, Claudia Cenedese +2
Iceberg meltwater is a critical freshwater flux from the cryosphere to the oceans. Global climate simulations therefore require simple and accurate parameterisations of iceberg mel…
Convective dynamics with mixed temperature boundary conditions: why thermal relaxation matters and how to accelerate it
Evan H. Anders, Geoffrey M. Vasil, Benjamin P. Brown +1
Astrophysical simulations of convection frequently impose different thermal boundary conditions at the top and the bottom of the domain in an effort to more accurately model natura…
