Magnetotelluric Response Distortion Over Rugged Topography
Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, ... 詳細を見る
3D Modeling of Fracture Flow in Core Samples Using ?-CT Data
Knowledge on flow behavior in fractured reservoir rocks is of great interest in petroleum engineering as well as for geothermal assets. Due to the big difference of magnitude (fracture aperture: ~?m, lateral extension of reservoirs ~km), modeling of discrete fracture flow is not ... 詳細を見る
BHE Field Design by Superposition of Effects in Space and Time
A design method for BHE fields in the absence of groundwater flow is presented, based on the superposition of effects. The effects of any periodic heat load with a period of one year can be obtained by a weighted sum of the effects of a monthly unit step heat load, properly displaced in ... 詳細を見る
Numerical Simulation of Temperature and Stress Fields in the Rock Heating Experiment
Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled ... 詳細を見る
Modeling Pit Lake Flooding After Mine Closure
Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming ... 詳細を見る
Using COMSOL for Optimal Design of Engineering Barriers of Nuclear Waste Repositories
The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering ... 詳細を見る
Reactive Transport Processes in Compacted Bentonite
The Swedish Organization for Radioactive Waste (SKB) is considering disposal High Level Wastes in a deep underground repository. Bentonite clay is planned to be used in the near-field of the waste packages as buffer material. The buffer is expected to provide a favorable environment with ... 詳細を見る
Investigation of Hydraulic Fracture Re-Orientation Effects in Tight Gas Reservoirs
In tight gas formations where the low matrix permeability prevents successful and economic production rates, hydraulic fracturing is required to produce a well at economic rates. As production from the well and its initial fracture declines, re-fracturing treatments are required to ... 詳細を見る
Designing Materials for Mechanical Invisibility Cloaks
In solid mechanics, there is considerable interest in achieving “invisibility”. The applications in mechanics include protection of structures and parts of structures from potentially harmful transient waves and steady state vibrations. A suggested large scale application is that ... 詳細を見る
Coupling Multiphysics with Geochemistry: The COMSOL-PhreeqC Interface
Phreeqc is a program for simulating chemical reactions and 1D transport processes in aqueous systems. Several couplings between conservative transport codes and PHREEQC already exist. The methodology used here is based on the operator splitting concept: the transport of the aqueous ... 詳細を見る
