Calculations and visualization presented by Pejvak Javaheri, Centre for Planetary Science Summer Intern, University of Toronto Scarborough, 2020

Mantle Convection in Spherical Annuli with an Arrhenius Rheology and a Rayleigh number of 10000

From top to bottom, rows correspond to geometry factors (Rcore/Rsurf) of 0.3, 0.4, 0.5, 0.6, and 0.7.

From left to right, each column corresponds to viscosity contrasts of 10^5, 10^6, and 10^7, respectively.

The surface temperature, reference temperature and activation energy are identical in all calculations. The maximum viscosity is capped at a maximum value that yields the indicated contrast. The minimum viscosity (at the core mantle boundary) is the same in all cases.
