Three-dimensional spherical shell convection at infinite Prandtl number using the ‘cubed sphere’ method
We present a new finite difference code for modeling three-dimensional thermal convection in a spherical shell using the “cubed sphere” method of Ronchi et al. [1]. The equation of motion is solved using a poloidal potential formulation for an iso-viscous, infinite Prandtl number fluid on a finite difference grid and advective transport is implemented using the 2nd-order MPDATA scheme of Smolar...
متن کاملWell-posedness of the Infinite Prandtl Number Model for Convection with Temperature-Dependent Viscosity
We establish the well-posedness of the infinite Prandtl number model for convection with temperature-dependent viscosity, free-slip boundary condition and zero horizontal fluxes.
متن کاملLow-degree mantle convection with strongly temperature- and depth-dependent viscosity in a three-dimensional spherical shell
A series of numerical simulations of thermal convection of Boussinesq fluid with infinite Prandtl number, with Rayleigh number 10, and with the strongly temperatureand depthdependent viscosity in a three-dimensional spherical shell is carried out to study the mantle convection of singleplate terrestrial planets like Venus or Mars without an Earth-like plate tectonics. The strongly temperature-d...

متن کاملApplication of the Yin-Yang grid to a thermal convection of a Boussinesq fluid with infinite Prandtl number in a three-dimensional spherical shell
A new numerical finite difference code has been developed to solve a thermal convection of a Boussinesq fluid with infinite Prandtl number in a three-dimensional spherical shell. A kind of the overset (Chimera) grid named “YinYang grid” is used for the spatial discretization. The grid naturally avoids the pole problems which are inevitable in the latitude-longitude grids. The code is applied to...
