Convective motions driven by core cooling have a structure that is three-dimensional and time-dependent. Consequently, the dynamics of the interaction between this flow and an underlying dense layer ...

A height-dependent model of the vertical eddy diffusivity for momentum, K(Z), has been formulated for purposes of studying numerically the momentum (and heat) transfer arising from turbulent motions ...

Our object in this article is to study the boundary layer appearing at large Reynolds number (small viscosity ε) in Oseen type equations in space dimension two in a channel. These are Navier-Stokes ...

Two geologists have provide different, though not necessarily incompatible, explanations for a boundary in Earth's mantle at a depth of one megameter (1,000 kilometers). One study suggests that the ...

The findings -- published today in the journal Nature Geoscience-- also may explain some deep earthquakes, hint that Earth's interior is hotter than believed, and suggest why partly molten rock or ...

Hauke Marquardt receives funding from the German Science Foundation DFG. Sinking tectonic plates get jammed in a newly discovered layer of the Earth’s mantle – and could be causing earthquakes on the ...

The boundary layer, a tiny layer on the surface of a body in a flowing fluid, such as an airplane wing in the air, is of paramount importance for the future of flight. Just over 100 years ago, Ludwig ...
