Electro-osmotic consolidation: Laboratory tests and numerical simulation
Electro-osmotic consolidation is an attractive soil improvement technique for soft clay. A review of research and practical applications of electro-osmosis was performed. The achievements and major bottleneck of the current technique were briefly discussed, and the potential areas for scientific research and engineering application were proposed. A laboratory testing facility was developed for ...
متن کاملDesign principle for improved three-dimensional ac electro-osmotic pumps.
Three-dimensional (3D) ac electro-osmotic (ACEO) pumps have recently been developed that are much faster and more robust than previous planar designs. The basic idea is to create a "fluid conveyor belt" by placing opposing ACEO slip velocities at different heights. Current designs involve electrodes with electroplated steps, whose heights have been optimized in simulations and experiments. Here...
متن کاملa numerical approach for one dimensional thermal consolidation of clays
in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...
متن کاملElectro-osmotic flow of a model electrolyte.
Electro-osmotic flow is studied by nonequilibrium molecular dynamics simulations in a model system chosen to elucidate various factors affecting the velocity profile and facilitate comparison with existing continuum theories. The model system consists of spherical ions and solvent, with stationary, uniformly charged walls that make a channel with a height of 20 particle diameters. We find that ...
متن کاملlaboratory assessment of the electro-osmotic consolidation technique for urmia lake sediments
the electro-osmotic consolidation is a method to improve geotechnical properties of soft clayey soils. the feasibility of electro–osmotically induced consolidation can be examined through the soil coefficient of electro–osmotic permeability (ke) and the electro–osmotic coefficient of water transport (ki). using an electro-osmotic testing cell, ke and ki parameters were measured in urmia lake we...
