Transport mechanisms of hydrothermal convection in faulted tight sandstones [PDF]
Solid Earth, 2023 Motivated by the unknown reasons for a kilometre-scale high-temperature overprint of 270–300 ∘C in a reservoir outcrop analogue (Piesberg quarry, northwestern Germany), numerical simulations are conducted to identify the transport mechanisms of the fault-

Evaporation of Nanofluid Sessile Droplets Under Marangoni and Buoyancy Effects: Internal Convection and Instability [PDF]
NanomaterialsPrevious research has studied the evolution of patterns during the evaporation of sessile droplets of pure liquid, although there is a lack of reports focusing on the transition of flow regimes and flow stability of nanofluids.

Crustal Conditions Favoring Convective Downward Migration of Fractures in Deep Hydrothermal Systems
Geophysical Research Letters, 2023 Cooling magma plutons and intrusions are the heat sources for hydrothermal systems in volcanic settings. To explain system longevity and observed heat transfer at rates higher than those explained by pure conduction, the concept of fluid convection in ...

Understanding controls on hydrothermal dolomitisation: insights from 3D reactive transport modelling of geothermal convection [PDF]
Solid Earth, 2020 The dominant paradigm for petrogenesis of high-temperature fault-controlled dolomite, widely known as “hydrothermal dolomite” (HTD), invokes upwelling of hot fluid along faulted and fractured conduits from a deep over-pressured aquifer.

Convection, but How Fast Does Fluid Mix in Hydrothermal Systems?
Geophysical Research LettersThe destabilizing thermal gradient across the Earth's lithosphere drives convection in superconfined hydrothermal environments at mid‐ocean ridges and geothermal reservoirs in the continental crust.

Large-scale groundwater flow and sedimentary diagenesis in continental shelves influence marine chemical budgets [PDF]
Nature CommunicationsThe major ion chemistry of the ocean has been assumed to be controlled by river input, hydrothermal circulation at mid-ocean ridges, carbonate production, and low-temperature alteration of seafloor basalt, but marine chemical budgets remain difficult to ...

Influence of External Magnetic Field on 3D Thermocapillary Convective Flow in Various Thin Annular Pools Filled with Silicon Melt [PDF]
Journal of Applied Fluid Mechanics, 2023 Thermocapillary convection flows can have an impact on the homogeneity of floating zone semiconductor crystals. An external magnetic field can also help to reduce this non-homogeneity.

Spatiotemporal structure of hydrothermal waves in Marangoni convection [PDF]
Physical Review E, 1993 When a liquid layer is laterally heated, the basic flow loses stability in the form of hydrothermal waves. They can be visualized by means of the shadowgraph technique. The characteristics of these waves are studied by performing the Fourier transform on a spatiotemporal diagram.

Hydrothermal waves in Marangoni convection in a cylindrical container [PDF]
Physical Review E, 1993 The features of hydrothermal waves that appear when a liquid layer is laterally heated are presented. A bifurcation is observed from a steady regime to a regime of a basic flow with superimposed traveling waves. Measured characteristics of waves are shown and compared with some recent theoretical predictions.

Effects of Deep Fluids on Middle Permian Dolomite of the Western Sichuan Basin
Frontiers in Earth Science, 2022 Deep fluid activity is closely related to carbonate reservoir transformation as well as oil and gas accumulation. The large-scale deep fluid activity caused by Emeishan large igneous province (ELIP) brought a lot of deep material and energy to Sichuan ...
