Onset of convection in fluids with strongly temperature-dependent, power-law viscosity
The onset of convection in the power-law creep regime on the terrestrial planets and icy satellites is poorly constrained. The major difficulty is that the viscosity of power-law fluids approaches infinity when the perturbation amplitudes approach zero and thus the methods of linear theory are inapplicable. Here, we determine the critical Rayleigh number for the onset of convection by starting ...
متن کاملOnset of convection with temperature- and depth-dependent viscosity
[1] We derive a scaling law for the onset of convection in an incompressible fluid cooled from above with temperatureand depth-dependent viscosity, on the basis of 2-D numerical simulation. Rayleigh numbers up to 10 are considered. The activation energy is varied from 0 to 200 kJ mol , and a variation of up to 10 is considered in depth-dependent reference viscosity. Our scaling law is shown to ...
متن کاملBifurcations in a convection problem with temperature-dependent viscosity
A convection problem with temperature-dependent viscosity in an infinite layer is presented. As described, this problem has important applications in mantle convection. The existence of a stationary bifurcation is proved together with a condition to obtain the critical parameters at which the bifurcation takes place. For a general dependence of viscosity with temperature a numerical strategy fo...
متن کاملOnset of convection in fluids with strongly temperature-dependent, power-law viscosity 2. Dependence on the initial perturbation
The onset of convection in the power-law creep regime on the silicate and icy planetary bodies requires a finite amplitude initial erturbation. This is a nonlinear problem and thus, both the amplitude and shape of the perturbation are important. We performed umerical simulations of the onset of convection in a two-dimensional layer with a fixed temperature contrast between the boundaries nd in ...
متن کاملSpectral numerical schemes for time-dependent convection with viscosity dependent on temperature
This article proposes spectral numerical methods to solve the time evolution of convection problems with viscosity strongly depending on temperature at infinite Prandtl number. Although we verify the proposed techniques just for viscosities that depend exponentially on temperature, the methods are extensible to other dependence laws. The set-up is a 2D domain with periodic boundary conditions a...
