Organic matter maturation in the contact aureole of an igneous sill as a tracer of hydrothermal convection

Journal of Geophysical Research: Solid Earth, 2015
The intrusion of magmas can induce hydrothermal convection which in turn enhances the transport of heat and solutes. We use a heat convection model to interpret the temperature evolution documented by organic matter maturation, as recorded by the ...

Hydrothermal Modelling and Analysis of Sensible Heat Energy Storages for Small-scale Dwellings Considering Natural Convection

Energy Procedia, 2016
The coupled hydrothermal behaviour of a cement-based thermal energy storage system for domestic applications is modelled under saturated conditions using the Finite Element Method along with an extensive experimental analysis program for parameter ...

Can high‐temperature, high‐heat flux hydrothermal vent fields be explained by thermal convection in the lower crust along fast‐spreading Mid‐Ocean Ridges?

Geochemistry, Geophysics, Geosystems, 2017
International audienceWe present numerical models to explore possible couplings along the axis of fast-spreading ridges, between hydrothermal convection in the upper crust and magmatic flow in the lower crust.

A model of hydrothermal convection in an aquifer

Journal of Geophysical Research: Solid Earth, 1980
Numerical calculations have been carried out to determine the temperature field due to the steady state hydrothermal flow of water through a smoothly curved cylindrical aquifer. It is found that the outflow water temperature relative to the ambient temperature at the base of the aquifer has a maximum at intermediate flow rates.

Convective Rolls and Hydrothermal Waves in Evaporating Sessile Drops

Langmuir, 2012
Recent experiments on the evaporation of sessile droplets have revealed the spontaneous formation of various patterns including the presence of hydrothermal waves. These waves had previously been observed, in the absence of evaporation, in thin liquid layers subjected to an imposed, uniform temperature gradient.

A study of hydrothermal convection in saturated porous media

Tectonophysics, 1993
Abstract Because of its relevance to many geological and technical problems, hydrothermal convection is investigated here mainly with the aid of numerical models by a systematic analysis of the properties of this type of convection for a range of super-critical Rayleigh numbers.

Hydrothermal wave instability of thermocapillary-driven convection in a coplanar magnetic field

Journal of Fluid Mechanics, 1997
We study the linear stability of surface-tension-driven unidirectional shear flow in an unbounded electrically conducting liquid layer heated from the side and subjected to a uniform magnetic field in the plane of the layer. The threshold of convective instability with respect to oblique travelling waves is calculated depending on the ...
