Modeling phase transport helps you study the multiphase flow through a porous medium (such as groundwater through soil).

Porous materials have complex geometries and may therefore be difficult to model. Setting up a microscale submodel is a useful approach to find the porosity and permeability of the medium.

Artificial ground freezing (AGF) is a valuable process in the construction industry. Researchers from China modeled groundwater flow to optimize an artificial ground freezing (AGF) process.

We go over a comprehensive selection of porous media and subsurface flow interfaces available to you in the COMSOL® software so that you can find the right choice for your modeling objective.

Today, guest blogger and Certified Consultant Ionut Prodan of Boffin Solutions, LLC discusses using a hybrid approach to calculate fracture flux in thin structures. When modeling thin fractures within a 3D porous matrix, you can efficiently describe their pressure field by modeling them as 2D objects via the Fracture Flow interface. Significant fracture flux calculation issues, however, may arise for systems of practical interest, such as hydraulic fractures contained within unconventional reservoirs. See how a hybrid approach overcomes such difficulties.

In order for groundwater to be useful for irrigation and drinking, we need to understand how its various solutes move through the water. The Subsurface Flow Module includes features for this.

The Well feature makes it easier to set up and mesh well geometries for subsurface flow modeling. Learn how to take advantage of this feature’s settings and capabilities.

To predict how a bank protection structure within the Yangtze River in China would deform under certain conditions, a group of researchers turned to geomechanical analysis.

When designing a perforated well to recover oil and gas, choosing the right number of perforations with the appropriate properties is key. Too many holes and you run the risk of equipment failure or injury; too few and you decrease productivity levels. One way to achieve this balance and improve the safety and productivity of the recovery operation is to model fluid flow near the wells. Let’s see how the Application Builder makes this process even more efficient.

Reservoirs, dams, and other outdoor structures need to be strong, reliable, and sound. The porous materials found within these structures can be easily damaged by pressure changes that cause fluid flow and gradual caving and sinking. Using the multiphysics simulation capabilities of COMSOL Multiphysics and the Poroelasticity interface, we can accurately analyze porous materials to evaluate and avoid deformation in such structures.
