Comparison of Simulation and Experimental Axial Loadings for Hydromechanical Bulge Forming of Copper Cross-Joints

open access: yesCommunications, 2005
Hydromechanical bulging is applied mainly to the series production of hydraulic installation and sanitary facilities including tubes with a changeable diameter, T-pipes and cross-joints.

Synergy of hydromechanical and hydrochemical parameters in formation of solid deposits in geothermal and other waters [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2014
This paper deals with synchronised influences of hydromechanical and hidrochemical parameters on the formation of solid deposits in geothermal and other waters which compose complex heterogeneous and micro-heterogeneous system of liquid-solid ...

A Method for Mathematical Modeling of Hydrodynamic Friction of Plunger Pairs with Consideration of Microgeometry

open access: yesMathematics, 2023
The fuel injection system heavily relies on the high-pressure fuel pump, which plays a critical role in its overall performance. The fuel pump plunger is subjected to high levels of stress and experiences irregular lubrication during dynamic loads ...

Quantifying Soft‐Surgery in Cochlear Implantation: Multimodal Data From 30 International Specialists

open access: yesThe Laryngoscope, EarlyView.
Objective data from 30 specialist cochlear implant surgeons showed that surgical handling strongly influences intracochlear mechanical stress during implantation. Surgeons with fewer than 50 lifetime insertions performed significantly worse than more experienced colleagues, while self‐assessment did not reflect objective performance in any group ...

On a hydromechanical theorem [PDF]

open access: yesProceedings of the Edinburgh Mathematical Society, 1889
Giffard's injector appeared more than thirty years ago. The first serious attempt to explain its action on dynamical principles was made by the late William Froude at the Oxford Meeting of the British Association in 1860. The history of mechanical science is almost everywhere deeply marked by Rankine; and it seems, just as it ought to be, that he ...

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

Phase-Field Modeling of Coupled Thermo-Hydromechanical Processes for Hydraulic Fracturing Analysis in Enhanced Geothermal Systems

open access: yesEnergies, 2023
Abundant geothermal energy can be harvested from deep, low-permeability rocks using an enhanced geothermal system (EGS) that relies on an artificially created permeable fracture network through cold water injection.

Rapid dehydration drives a nondiffusional drop in C3 photosynthesis that aligns with phosphate limitation

open access: yesNew Phytologist, EarlyView.
Schematic representation of the causal sequence through which rapid water loss imposes diffusive and nondiffusive restrictions on carbon assimilation. Summary Drought is an abnormally prolonged water deficit posing major challenges to plants. Stomatal closure has long been considered the primary factor limiting photosynthesis during the early stages of

Modeling hydraulic cracks and inclusion interaction using XFEM

open access: yesUnderground Space, 2018
In this study, we employ a coupled hydromechanical model to study the hydraulic fracture propagation path in porous media under the influence of existing pressurized voids.

Experimental Study on Deformation Behavior and Permeability Evolution of Sandstone Responding to Mining Stress

open access: yesEnergies, 2022
Mining-induced hydromechanical behavior of sandstone is critical to mining safety and disaster prevention. To investigate the evolution behavior of the mechanical and permeability properties of sandstone, mining-induced stress was imitated by increasing ...
