Numerical Model for Leaching and Transporting Behavior of Radiocesium in MSW Landfill
This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for ... Read More
Simulation of Reactive Transport in Porous Media: A Benchmark for a COMSOL-PHREEQC-Interface
The reactive transport simulation interface COMSOL-PHREEQC, developed by Wissmeier & Barry (2011), provides a MATLAB®-based coupling interface to combine COMSOL Multiphysics® for flow and heat transport simulations and PHREEQC as a geochemical batch reaction simulator. The ... Read More
Stability of an Underground Limestone Mine
The hills of South-Limburg, the Netherlands, are crisscrossed with underground limestone mines. These "caves" are not equally stable, and can be dangerous. With COMSOL Multiphysics® a stability assessment has been made. The first study examines the full stress and displacement profile ... Read More
Modelling Reservoir Stimulation in Enhanced Geothermal Systems
Fluid injection in deep wells is a basic procedure in geothermal permeability enhancement. The retrieved changes of Pressure and Temperature are subsequently considered as sources of incremental stress and strain changes, using the elastic model from COMSOL Multiphysics®, which are then ...

Developments in a Coupled Thermal-Hydraulic-Chemical-Geomechanical Model for Soil and Concrete
This paper documents current status in the development of a coupled thermal-hydraulic-chemical-geomechanical numerical suite within COMSOL-MATLAB environment to address soil and concrete applications. The mathematical formulations are based on well-established continuum scale models ... Read More
Applicability of the Fracture Flow Interface to the Analysis of Piping in Granular Material
Piping is a kind of internal erosion that occurs under water retaining structures lying on a sandy soil. In an attempt to reproduce the growth of erosion channels in sand, a small scale physical model has been set up in the laboratory and a finite element model that reproduces the ... Read More
Reactive Transport and Convective Mixing During CO2 Migration in a Saline Aquifer
The capture and storage of CO2 in deep geological formations is one of the proposed solutions to reduce CO2 emissions to the atmosphere. CO2 is injected as a supercritical fluid deep below a confining geological formation that prevents its return to the atmosphere. A configuration of ... Read More
Oscillatory Thermal Response Test (OTRT) – An Advanced Method for Gaining Thermal Properties of the Subsurface
Thermal Response Tests (TRTs) are the state-of-the-art method to obtain the thermal conductivity of the subsurface in the nearby ambience of a borehole heat exchanger (BHE). The results of TRTs are used to determine the necessary depth of the borehole and to make long time predictions ... Read More
Investigating the Impacts of Hydrogeological Parameters on DSI Efficiency through Numerical Simulation
Düsensauginfiltration (DSI),‘nozzle-suction-infiltration’, is a new method for dewatering that avoids groundwater abstraction from the aquifer. Drawdown is achieved via pumping of groundwater at upper abstraction section, meanwhile, all the pumped water is injected through the same ... Read More
Full Coupling of Flow, Thermal and Mechanical Effects in COMSOL Multiphysics® for Simulation of Enhanced Geothermal Reservoirs
The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... Read More
