Numerical Simulation of Hydrothermal Autoclave for Single-Crystal Growth Process
Journal of Thermal Science and Technology, 2008 Numerical simulation of the hydrothermal process for growing two-inch bulk single crystals of ZnO has been done. The autoclave is assumed to be axisymmetric. The heat transfer by natural convection is discussed for flat and funnel-shaped baffles.

Influence of Convection Term on Temperature Field during Soil Freezing
Buildings, 2022 In recent years, the numerical model of frozen soil has mainly focused on the water-heat equation of unsaturated soil, which is of great significance to predicting engineering stability in frozen soil areas.

An experimental analogue for convection and phase separation in hydrothermal systems [PDF]
Journal of Geophysical Research: Solid Earth, 2006 Experiments were conducted to explore the behavior of convection and heat transfer during phase separation in porous media. Phase separation is considered to be an important process in many mid‐ocean ridge hydrothermal systems in which a dense brine separates from a lighter, less saline vapor phase at supercritical temperatures.

A Macroscale Hydrogeological Numerical Model of the Suio Hydrothermal System (Central Italy)
Geofluids, 2019 The complex behaviour of the Suio hydrothermal system (central Italy) and its potential exploitation as a renewable energy source are still unclear. To quantitatively evaluate the geothermal resource, the Suio hydrothermal system has been investigated ...

ROLE OF ANISOTROPIC AND/OR LAYERED PERMEABELITY IN HYDROTHERMAL CONVECTION
Geophysical Research Letters, 1990 The spatial variation and degree of anisotropy of the permeability field (k) is an important parameter affecting the dynamics of convective fluid flow in saturated geologic media. We report results from time‐dependent, two‐dimensional numerical simulations, with constant fluid properties, for k fields that are anisotropic, layered or both.

Study of Fe3O4-water nanofluid with convective heat transfer in the presence of magnetic source
Alexandria Engineering Journal, 2018 Influence of external magnetic source on ferrofluid convection in an enclosure with elliptic hot cylinder is studied. Governing formulae are first made dimensionless form along with the associated boundary conditions and then solved by powerful numerical

Natural convection and the evolution of a reactive porous medium
, 2011 We describe a mathematical model of buoyancy-driven flow and solute transport in a saturated porous medium, the porosity and permeability of which evolve through precipitation and dissolution as a mineral is lost or gained from the pore fluid. Imposing a
