We optimized potential parameters in a molecular dynamics model to reproduce the experimental contact angle of a macroscopic mercury droplet on graphite. With the tuned potential, we studied the effects of pore size, geometry, and temperature on the wetting of mercury droplets confined in organic-rich shale nanopores. The contact angle of mercury in a circular pore increases exponentially as po...

a series of tests and also numerical analyses were conducted to explore the mechanical behavior of a mixture of coarse gravelsize particles floating in a matrix of silt, sand or clay. the research is a step forward in an ongoing investigation on behavior of composite clay, which is used as the core material of some large embankment dams all over the world. after providing the reader with an ove...

Insight in the biogeochemistry and ecology of sandy sediments crucially depends on a quantitative description of pore water flow and the associated transport of various solutes and particles. We show that widely different problems can be modelled by the same flow and tracer equations. The principal difference between model applications concerns the geometry of the sediment-water interface and t...

River bed and bank protections should be designed regarding unsaturated soil conditions. Natural surface and pore water are not ideal incompressible fluids. Microscopic gas bubbles are dispersed in both of them. Due to the compressibility of such fluids delayed pore water reactions can be observed when external pressure changes act on such a medium. This paper deals with the results of laborato...

This paper shows the results of a field appliance study hydraulic well method to prevent embankment piping, which is proposed by Japanese Matsuyama River National Highway Office. The large-scale experiment and seepage analysis were conducted examine well. experimental procedure focused on pore water pressure. levels compared with pressure data, used look over variations. Two different types exp...

Grand canonical Monte Carlo simulations are performed to study the adsorption of water in single-walled (6:6), (8:8), (10:10), (12:12), and (20:20) carbon nanotubes in the 248-548 K temperature range. At room temperature the resulting adsorption isotherms in (10:10) and wider single-walled carbon nanotubes (SWCNs) are characterized by negligible water uptake at low pressures, sudden and complet...
