Book ChapterDOI
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.
Journal ArticleDOI
Concepts and models of dolomitization: a critical reappraisal
TL;DR: A review of the state of the art in dolomite research can be found in this article, where the authors highlight the major advances and controversies of the last 20-25 years.
Journal ArticleDOI
The thermal conductivity of seasonal snow
TL;DR: In this article, the authors present a new data set containing 488 measurements for which the temperature, type and measurement accuracy are known, and show that there are well-defined limits to the geometric configurations that natural seasonal snow can take.
Journal ArticleDOI
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.
Journal ArticleDOI
Basin Evaluation by Integrated Two-Dimensional Modeling of Heat Transfer, Fluid Flow, Hydrocarbon Generation, and Migration
TL;DR: The basin model discussed in this article describes the physical and chemical phenomena that control the formation of commercial accumulations of hydrocarbons in the moving framework of a subsiding sedimentary basin: heat transfer, compaction and water flow, hydrocarbon generation, and two-phase migration of fluids.

Journal ArticleDOI
Convection of a fluid in a porous medium
TL;DR: 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.
Journal ArticleDOI
Convection Currents in a Porous Medium
C. W. Horton,F. T. Rogers +1 more
TL;DR: In this paper, it was shown that the minimum temperature gradient for which convection can occur is approximately 4π2h2μ/kgρ0α D2, where h2 is the thermal diffusivity, g is the acceleration of gravity, μ is the viscosity, k is the permeability, α is the coefficient of cubical expansion, ρ 0 is the density at zero temperature, and D is the thickness of the layer; this exceeds the limiting gradient found by Rayleigh for a simple fluid by a factor of 16D2/27π2
Journal ArticleDOI
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.
Journal ArticleDOI
Finite amplitude cellular convection
W. V. R. Malkus,G. Veronis +1 more
TL;DR: In this paper, a method for determining the form and amplitude of a layer of convection is presented, where the non-linear equations describing the fields of motion and temperature are expanded in a sequence of inhomogeneous linear equations dependent upon the solutions of the linear stability problem.
