TLDR
In this article, it was shown that under certain conditions convective flow may occur in fluid which permeates a porous stratum and is subject to a vertical temperature gradient, on the assumption that the flow obeys Darcy's law.Abstract:
It is shown that under certain conditions convective flow may occur in fluid which permeates a porous stratum and is subject to a vertical temperature gradient, on the assumption that the flow obeys Darcy's law. The criterion for marginal stability is obtained for three sets of boundary conditions, and the motion described. If such convection occurs in a stratum through which a bore-hole passes, the usual method of calculation of the heat flow must be modified, but in general the correction will not be large.read more

Heat as a ground water tracer.
TL;DR: Ground water temperature data and associated analytical tools are currently underused and have not yet realized their full potential, according to this review paper.

Heat Transfer in Geothermal Systems
TL;DR: In this paper, the authors discuss the mathematical formulation of convective heat transfer in geothermal systems and the prediction of reservoir behavior under production can be obtained by idealizing it as a saturated porous medium.

Onset of Thermohaline Convection in a Porous Medium
TL;DR: In this article, the problem of the onset of convection, induced by buoyancy effects resulting from vertical thermal and solute concentration gradients, in a horizontal layer of a saturated porous medium, is treated by linear perturbation analysis.

On the Thermal Balance of a Mid‐Ocean Ridge
TL;DR: In the Juan de Fuca Ridge and Explorer Trough, the mean heat flow was found to be near 7 HFU (290 mW m−2) as mentioned in this paper, which is close to the expected from conductive heat-flow refraction.

Variable-density flow and transport in porous media: approaches and challenges
H.-J.G. Diersch,Olaf Kolditz +1 more
TL;DR: Weaknesses and inconsistencies of current model-verification methods are discussed as well as benchmark solutions for solving the coupled spatio-temporal convection process, consistent velocity approximation, and error-based mesh adaptation techniques.

On the flow of water in an elastic artesian aquifer
TL;DR: Meinzer as mentioned in this paper showed that the amount of water discharged from storage could not be accounted for on the basis of the compressibility of water alone, but that it might be explained by the probable compressibility properties of the sandstone itself.

TL;DR: In this article, the stability in viscous liquid of a steady regime in which the temperature decreases with uniform gradient between a lower horizontal surface which is heated and an upper horizontal surface that is cooled is examined.

Heat Flow in South Africa
TL;DR: Benfield and Weiss as discussed by the authors measured the conductivities of specimens of rock from some of the boreholes in which temperature measurements had been made, and discussed the results of these measurements.
