Application ID: 258
Dialysis is a widely used chemical species separation method. One such example is hemodialysis, which acts as artificial kidneys for people with renal failure. In dialysis, only specific components are allowed to diffuse through the membrane, based on differences in molecular size and solubility.
The Membrane Dialysis app simulates a process for lowering contaminant concentration in a fluid. The device consists of a hollow fiber module, where the walls of the hollow fibers act as a membrane for removing the contaminant.
Results from this app can aid in selecting membrane materials, dimensions of the fibers, and operating conditions.
This application example illustrates applications of this type that would nominally be built using the following products:Chemical Reaction Engineering Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- Batteries & Fuel Cells Module, CFD Module, Chemical Reaction Engineering Module, Corrosion Module, Electrochemistry Module, Electrodeposition Module, or Subsurface Flow 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.
