In this study, we propose an absorbing boundary domain (or condition), which is really simple but still efficient for the 2.5D finite element (FE) analysis. The main application is to simulate the electromagnetic (EM) waves related to the marine controlled source electromagnetic (CSEM) ... Per saperne di più
钻井时,泥浆滤液会在压力差的作用下侵入到渗透性地层,地层水的饱和度与矿化度发生改变,从而测量的电阻率数值偏离地层电阻率。 长方体模拟地层,三个圆分别模拟供电和测量电极,参数设定坐标。 地下水流模块中Two-Phase Darcy’s Law接口模拟泥浆侵入,两相流体密度和黏度,固体孔隙度与绝对渗透率都通过空白材料赋值,地层上下无流动,设定地层初始压力和流体饱和度,左侧边界设定侵入压力和流体饱和度,右侧边界设定出口压力。 化学模块中的Transport of diluted species in porous media计算泥浆侵入后地层水矿化度 ... Per saperne di più
In a pumping test the drawdown of the water table in a piezometer is recorded, as response to pumping from a nearby well. Pumping tests belong into the common toolbox of hydro-geologists, used to obtain basic parameters for aquifer characterization. There are various approaches to ... Per saperne di più
Bentonite is a versatile material that is, among other things, envisaged in designs for radioactive waste repositories to protect the waste canisters against groundwater. The thermo-hydraulic-mechanically coupled process of bentonite saturation is commonly based on two-phase flow and a ... Per saperne di più
Spectral Induced Polarization (SIP) is a geophysical technique that measures the frequency dependence of the electrical conductivity of a material. The potential of using SIP to predict the hydraulic conductivity of the ground has been investigated since 1950s. However, the dependency of ... Per saperne di più
Modeling of fractured porous media systems is currently of high interest in various academic and applied fields, mainly in the geological and material sciences. The very different scales of the region of an application case on the larger end and the fracture on the lower end pose a ... Per saperne di più
For hydrogeologists pumping tests are the most common method to obtain characteristic aquifer properties, like transmissivity and storativity. For the evaluation of pumping tests it is common practice to compare field measurements and 1D analytical solutions. Numerical methods offer the ... Per saperne di più
In plate tectonics, the relative motion between plates at a plate boundary generates tectonic stress, and most earthquakes occur at these plate boundaries. However, only a small proportion of earthquakes occur in plate interiors, such as the 1811–12 New Madrid Earthquake (8.1 Mw) in the ... Per saperne di più
Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ...

Subduction, the process through which the cold and dense oceanic lithosphere sinks into the highly viscous mantle, is the main driving force of plate tectonics and is important for recycling the Earth's materials. Active subduction has not been observed in any other planet in our solar ... Per saperne di più
