Two-Phase Flow in Column
Application ID: 499
The first model describes the simultaneous flow of two immiscible fluids in porous media - here air displaces water in a multi-step inlet pressure experiment. We solve for the pressure and the degree saturation for the air and water within a representative volume and so track saturation levels rather than estimating a discrete location for the air-water interface.
A second example is also available for air and oil and builds on the above two-phase flow model for an air-water system. The switch from air-water to air-oil is accomplished with Leverett scaling of interfacial tensions for the different fluid pairs.
The final example of oil-water flow, from a multi-step inlet pressure experiment, builds on the two-phase flow model for an air-water system. The inlet pressure steps were evaluated with Leverett scaling of interfacial tensions for the different fluid pairs.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
