Application ID: 515
This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into air.
The concentration profiles are modeled at steady-state and validated against experimental data by Taylor and Krishna (1993).
This model is included as an example in the following products:Chemical Reaction Engineering Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
- COMSOL Multiphysics® and
- either the Batteries & Fuel Cells Module, CFD Module, or Chemical Reaction Engineering Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
