Abstract

A finite element code is developed for a thermal convection problem of infinite Prandtl number Boussinesq fluid subject to slip velocity boundary conditions. The problem is a fundamental mathematical model of the Earth's mantle movement. It is described by a couple of the Stokes equations and the convection-diffusion equation combined by buoyancy and convection terms. A stabilized finite element scheme with P1/P1/P1 element is employed. Some numerical computations in a three-dimensional spherical shell with Rayleigh number 10 4 are performed. Time histories of the Nusselt numbers and the root-mean-square velocities are computed, which are observed to be convergent as the mesh subdivisions become finer.
