Heat transport by variable viscosity convection and implications for the Earth's thermal evolution
TLDR
In this article, an extensive numerical study of the heat transport by 2-D steady state convection with free boundaries and temperature dependent viscosity was carried out, and the results for convection in a square box were presented in several ways.About:

Scaling of temperature‐ and stress‐dependent viscosity convection
TL;DR: In this article, a simple scaling analysis of temperature and stress-dependent viscosity convection with free-slip boundaries suggests three convective regimes: the small contrast regime, the transitional regime, and the asymptotic regime.
Journal ArticleDOI
Role of temperature‐dependent viscosity and surface plates in spherical shell models of mantle convection
TL;DR: In this article, the authors show that long-wavelength structures can be produced either by a layered viscosity with a weak upper mantle or temperature-dependent viscosities even in the absence of surface plates.
Journal ArticleDOI
Numerical investigation of 2D convection with extremely large viscosity variations
TL;DR: In this article, a finite element multigrid scheme was employed for large viscosity variations and convection with up to 1014 contrasts was systematically investigated in a 2D square cell with free slip boundaries.
Journal ArticleDOI
Self-consistent generation of tectonic plates in time-dependent, three-dimensional mantle convection simulations
TL;DR: In this article, self-consistent, three-dimensional simulations of mantle convection are presented, some of which display an approximation of plate tectonic behavior that is continuous in space and time.
Journal ArticleDOI
The generation of plate tectonics from mantle convection
TL;DR: In the last decade, significant progress has been made toward understanding how plate tectonics is generated from mantle dynamics as discussed by the authors, which has led to plate-like segments separated by narrow, weak and rapidly deforming boundaries.

The heat flow through oceanic and continental crust and the heat loss of the Earth
TL;DR: In this paper, the authors used radiometric dates to estimate the amount of heat lost by the earth during the last orogenic event, the distribution of heat-producing elements, and erosion.

Finite amplitude convective cells and continental drift
Donald L. Turcotte,E. R. Oxburgh +1 more
TL;DR: In this paper, a solution was obtained for steady, cellular convection when the Rayleigh number and the Prandtl number are large, and the theory was used to test the hypothesis of large scale convective cells in the earth's mantle.

A study of Bénard convection with and without rotation
TL;DR: In this article, an experimental study of the response of a thin uniformly heated rotating layer of fluid is presented, and it is shown that the stability of the fluid depends strongly upon the three parameters that described its state, namely the Rayleigh number, the Taylor number and the Prandtl number.

Mantle convection and the thermal structure of the plates
Barry Parsons,Dan McKenzie +1 more
TL;DR: In this article, a more realistic model is developed, based on the idea that the thermal structure of the plate becomes unstable and leads to the development of small-scale convection, which then supplies the heat flux needed to match the observations rather than an artificial constant temperature boundary condition.

Convection with pressure- and temperature-dependent non-Newtonian rheology
TL;DR: In this article, the influence of non-linear stress-strain rate relation on thermal convection in a fluid whose rheological properties are also pressure-and temperature-dependent is studied in a series of numerical models.
