Hydrothermal Instability Of Thermocapillary Convection In Large-Prandtl-Number Liquid Bridges Under Microgravity [PDF]
, 2008 Linear stability analysis was performed to study the mechanism of transition of thermocapillary convection in liquid bridges with liquid volume ratios ranging from 0.4 to 1.2, aspect ratio of 0.75 and Prandtl number of 100.

Geochemistry, Geophysics, Geosystems, 2021 The clastic‐dominant (CD‐type) deposits that are contained within sedimentary basins are major resources of Zn, Pb and Ag, but their formation by basin‐scale hydrothermal mass and energy transport processes is still poorly understood.

Geothermal Energy, 2019 Hydrothermal convection in porous geothermal reservoir systems can be seen as a double-edged sword. On the one hand, regions of upflow in convective systems can increase the geothermal energy potential of the reservoir; on the other hand, convection ...

Hydrothermal Wave in a Shallow Liquid Layer [PDF]
, 2005 The oscillatory thermocapillary convection and hydrothermal wave in a shallow liquid layer, where a temperature difference is applied between two parallel sidewalls, have been numerically investigated in a two-dimensional model.

Ceres’ Broad‐Scale Surface Geomorphology Largely Due To Asymmetric Internal Convection
AGU Advances, 2022 While we now know much about the volatile‐rich world of Ceres from the Dawn mission, the deep interior remains something of an enigma, shrouded by a crust composed of water ice, carbonates, phyllosilicates, salts and clathrate hydrates.

Chaotic thermohaline convection in low-porosity hydrothermal systems [PDF]
Earth and Planetary Science Letters, 1999 Fluids circulate through the Earth's crust perhaps down to depths as great as 5^15 km, based on oxygen isotope systematics of exhumed metamorphic terrains, geothermal fields, mesozonal batholithic rocks and analysis of obducted ophiolites. Hydrothermal flows are driven by both thermal and chemical buoyancy; the former in response to the geothermal ...

Temperature oscillations of hydrothermal waves in thermocapillary-buoyancy convection [PDF]
Physical Review E, 1999 We report an experimental study of a fluid layer of Prandtl number Pr510.3 subject to a horizontal temperature gradient with the surface open to the air. For certain values of the control parameters ~fluid depth and temperature difference! the basic flow is destabilized and a pair of so-called oblique hydrothermal waves is observed.

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 ...
