A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. Simulations created in COMSOL Multiphysics® software are also presented to corroborate the shooting method and display ...

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 reservoir engineering, bio-engineering, environmental engineering etc. We have used quasi-static poroelastic ...

A model is presented for heat rejection in the subsurface. Geometries of different dimension are coupled by linear and general extrusions. In that way it is possible to deal with multi-scale physical set-up. An example shows the high influence of groundwater flow.

Groundwater is a key factor affecting mine operations worldwide. On one hand, both underground and open pit mines need to pump out groundwater in order to proceed with mineral extraction and increase the stability of rock slopes. On the other hand, groundwater abstractions can produce undesired environmental and social impacts, which should be anticipated in the environmental impact assessments ...

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 borehole, but in greater depth. We use COMSOL Multiphysics® for the development of a 2D model that simulates ...

To reveal key features of the thermal pattern at different structural levels of the Norwegian continental shelf and the adjacent mainland, the lithosphere-scale 3D structural models have been used to represent a structure of the sedimentary cover, underlying crystalline crust, and lithospheric mantle during a 3D thermal modeling. For the construction of these 3D models, all available geological ...

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...

Non-conventional hydrocarbon resources become more and more challenging object for energy producing companies throughout the world. Being already known and long-explored method, the electromagnetically (EM) assisted recovery constitutes a promising idea of technology for deposits of such a kind. COMSOL has been used recently for modeling the thermal multiphase flow through porous media in the ...

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 different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...
