Geothermal systems occur in a range of crustal settings. The emphasis of this review is on
those occurring in regions of active or recently active volcanism, where magmatic heat at …

We review the state of the art in modeling of variable-density flow and transport in porous
media, including conceptual models for convection systems, governing balance equations …

Publisher Summary This chapter discusses the mathematical formulation of the problems of
convective heat transfer in geothermal systems. Geothermal reservoirs may have numerous …

Modeling of flow and transport in groundwater has become an important focus of scientific
research in recent years. Most contributions to this subject deal with flow situations, where …

Natural convection flows in a square cavity filled with a porous matrix has been studied
numerically using penalty finite element method for uniformly and non-uniformly heated …

Convection in a porous cavity driven by heating in the horizontal is analysed by a number of
different techniques which yield a fairly complete description of the two-dimensional …

Water‐rock interactions within the seafloor are responsible for significant energy and solute
fluxes between basaltic oceanic crust and the overlying ocean. Permeability is the primary …

Generally, when the density of the saturating fluid phase in a porous medium is not uniform,
some movements caused by the effect of gravity forces may occur and tend to reduce the …

Convective groundwater motion can be generated in aquifers beneath and adjacent to
saline lakes. Such motions strongly control the subsurface distribution of salts, the formation …

This work continues the analysis of variable density flow in groundwater systems. It focuses
on both thermohaline (double-diffusive) and three-dimensional (3D) buoyancy-driven …
