Scaling behaviour of rotating convection in a spherical shell with different Prandtl numbers
Wei Fan, Qi Wang, Yufeng Lin
Rayleigh-Benard convection in a rotating spherical shell provides a simplified model for convective dynamics of planetary and stellar interiors. In this study, we build more than 2…

Weakening the effect of boundaries: `diffusion-free' boundary conditions as a `do least harm' alternative to Neumann
Yufeng Lin, Rich Kerswell
In this note, we discuss a poorly known alternative boundary condition to the usual Neumann or `stress-free' boundary condition typically used to weaken boundary layers when diffus…
