Self-potential effects due to hydrothermal convection-velocity crosscoupling [PDF]

, 1982
The modeling of self-potential effects by the use of electric and convection currents is readily adaptable to the problem of crosscoupled flows due to hydrothermal convection. In this modeling of the electrokinetic effects, all that is required is a velocity model and models of the crosscoupling parameters and the electric conductivity.

Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

Investigating Breathing Dynamics of a 110 kV Oil‐Immersed Transformer Using Thermal‐Fluid‐Structure Interaction Modelling

High Voltage, EarlyView.
ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Growth Method-Dependent and Defect Density-Oriented Structural, Optical, Conductive, and Physical Properties of Solution-Grown ZnO Nanostructures

Nanomaterials, 2017
It is time for industry to pay a serious heed to the application and quality-dependent research on the most important solution growth methods for ZnO, namely, aqueous chemical growth (ACG) and microwave-assisted growth (MAG) methods.

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.

Anisotropic Modelings of the Hydrothermal Convection in Layered Porous Media.

Journal of Physics of the Earth, 1992
Equivalence of anisotropic modelings of the hydrothermal convection to the layered permeability distribution is examined by 2-D numerical imulations. Permeability varies sinusoidally in horizontal or vertical directions. For the horizontally layered cases, flow fields approach monotonically to the corresponding anisotropic models, as the wavelength of ...

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.

Effect of SSZ‐13 Zeolite Loading and Synthesis Time on the CO2/N2 Separation Performance of PDMS Mixed Matrix Membranes

Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.
Advantages of MMMs and the Robeson plot detailing improved performance of the 4d05% membrane. ABSTRACT Mixed matrix membranes were produced by incorporation of SSZ‐13 zeolites into polydimethylsiloxane (PDMS) to assess the effect of filler properties and concentration on the CO2/N2 separation efficiency compared to pure PDMS membranes.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Three‐dimensional seismic structure of the Dragon Flag oceanic core complex at the ultraslow spreading Southwest Indian Ridge (49°39′E)

Geochemistry, Geophysics, Geosystems, 2013
The Southwest Indian Ridge (SWIR) is an ultraslow spreading end‐member of mid‐ocean ridge system. We use air gun shooting data recorded by ocean bottom seismometers (OBS) and multibeam bathymetry to obtain a detailed three‐dimensional (3‐D) P wave ...
