Diffusion-Free Dynamics in Rotating Spherical Shell Convection Driven By Internal Heating and Cooling
Neil T. Lewis, Tom Joshi-Hartley, Steven M. Tobias +2
The bulk properties of convection in stellar and giant planet interiors are often assumed to be independent of the molecular diffusivities, which are very small. By contrast, simul…

Model of deep zonal flows in giant planets
Laura K. Currie, Chris A. Jones
A mechanism by which the surface zonal flows of giant planets can be gradually attenuated with depth is explored. The zonal flow is driven by an imposed forcing in a thin layer nea…

Heat Transport and Dissipation in 2.5D Rotating Internally Heated and Cooled Convection
Tom Joshi-Hartley, Matthew K. Browning, Laura K. Currie +3
Models of astrophysical convection, such as mixing length theory, typically assume that the heat transport is independent of microphysical diffusivities. Such 'diffusion-free' beha…
