For the numerical solving of the equations, Comsol has been applied. Simulations have been modeled in 2D Cartesian, in cylindrical coordinate system and in a “mantle-like” cylindrical-shell. Mantle dynamics is controlled by the Rayleigh number (Ra), which is the ratio of the buoyancy ... 詳細を見る

There are only two types of naturally-occurring earthquakes anywhere on the Earth: 1) those associated with the dynamics of plate tectonics and 2) those associated with the dynamics of the hydrologic cycle. The first type is characteristic of an INTERplate setting (like the San Andreas ... 詳細を見る

Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in ... 詳細を見る

The Solargeotherm project is assessing the possibility of using vertical geothermal probes drilled into a rock mass (bedrock) for storing the thermal energy produced by solar panels and later releasing it. The research project relies on the installation of an experimental system and the ... 詳細を見る

Using a 1-D model of polymer displacement, we analyze the exergy (maximum attainable work) balance of viscosified water, e.g. with Arabic gum. The 1-D model shows the principle how such an analysis can be done. A comparison as to the displacement efficiency is made between three ... 詳細を見る

Introduction: This study presents the 3D electromagnetic model in layered media using induction logging tool. This algorithm utilizes electromagnetic wave frequency domain (EWFD) interface of Maxwell equations. Electromagnetic methods are popular tools for the measurement of resistivity ... 詳細を見る

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... 詳細を見る

Soil’s electromagnetic properties adversely affect the performance of electromagnetic induction (EMI) sensors and if conditions are severe enough, render them useless. A simple circuit model is often used to express the electromagnetic induction response of a target analytically. This ... 詳細を見る

Injection conditions of CO2 at the wellhead may play a major role on the flow behavior through the wellbore. The density and the injection rate reached at the bottomhole are key factors affecting the performance and efficiency of CO2 geological storage. In this work, a model of non ... 詳細を見る

Injection of 3-D hot plume blob develops localized and short-term increases in slab surface temperatures, consistent with the Abukuma adakite, Northeast Japan. 3-D mantle flow develops trough of the lowered slab surface temperatures implying along lowered slab surface temperatures, ... 詳細を見る
