In this work, we use the transient time correlation function (TTCF) method to evaluate the response of a fluid confined in a nanopore and subjected to shear. The shear is induced by the movement of the boundaries in opposite directions and is made of moving atoms. The viscous heat generated inside the pore is removed by a thermostat applied exclusively to the atomic walls, so as to leave the dy...

This paper presents a new approach to study the effects of temperature on the poroelastic and viscoelastic behavior of articular cartilage. Biphasic solid-fluid mixture theory is applied to study the poro-mechancial behavior of articular cartilage in a fully saturated state. The balance of linear momentum, mass, and energy are considered to describe deformation of the solid skeleton, pore fluid...

Pore-scale forces have a significant effect on the macroscopic behaviour of multiphase flow through porous media. This paper studies the effect of these forces using a new volume-of-fluid based finite volume method developed for simulating two-phase flow directly on micro-CT images of porous media. An analytical analysis of the relationship between the pore-scale forces and the Darcy-scale pres...

The mitochondrial permeability transition (PT) pore, also called the mitochondrial megachannel, is a multiprotein complex formed at the contact site between the mitochondrial inner and outer membranes, exactly the same location at which Bax, Bcl-2 and Bcl-XL are particularly abundant. The PT pore participates in the regulation of matrix Ca2+, pH, transmembrane potential and volume, and function...

The settlement rate and pore water pressure dissipation are mainly controlled by the permeability of soil. Both laboratory field tests show that is varied during loading consolidation process. It known process accompanied decrease in void ratio which leads to coefficient permeability. importance on time needs be investigated.This paper takes into account change studies its effect characteristic...

The design of underground spaces is mainly carried out using empirical, analytical, and numerical methods. The convergence confinement method (CCM) is an analytical technique that is widely utilized in analyzing the stability of underground spaces. However, the main challenge in the stability analysis is the selection of an accurate constitutive model for rock mass, and particularly, its post-f...

Tides have been recognized as a major driving forcing affecting coastal aquifer system, and deterministic modeling has been very effective in elucidating mechanisms caused by tides. However, such modeling does not lend itself to capture embedded information in the signal, and rather focuses on the primary processes. Here, using yearlong data sets measured at beaches in Alaska Prince William Sou...

Stone column replacement of soft soil foundation construction method is more and used in water conservancy projects. On the one hand, stone has high permeability, which enhances dissipation capacity excess pore pressure; on other it a stiffness, reduces additional stress soil, therefore pressure. These two mechanisms work together to improve bearing soil. In previous plane strain transformation...

The study on the mechanical response of deep rock under hydromechanical couplings condition can guide safe excavation and stability evaluation tunnel engineering. effects monotonic loading cyclic properties granite 5 MPa pore water pressure 10 confining were studied by laboratory tests. Before peak stress, permeability was significantly higher than that loading, increased sharply after stress. ...

Control of water and air in the root zone of plants remains a challenge in the microgravity environment of space. Due to limited flight opportunities, research aimed at resolving microgravity porous media fluid dynamics must often be conducted on Earth. The NASA KC-135 reduced gravity flight program offers an opportunity for Earth-based researchers to study physical processes in a variable grav...
