Numerical experiments on the convection in compressible media
Abstract
The consequences for compressible convection flows of the recently formulated depth dependence of the thermodynamic parameters of the Earth mantle, were studied. Convection flows as well as convection in the high grade nonlinear domain of higher supercritical Rayleigh numbers were investigated using stationary and time dependent numerical models. At higher dissipation numbers and/or higher surface temperatures differences are found between the present model and models using constant thermodynamic parameters. The depth dependence of these parameters also has important consequences for the dynamics of the lower Earth model and the D layer.
