Galeria de Modelos

The Model Gallery features COMSOL Multiphysics model files from a wide variety of application areas including the electrical, mechanical, fluid, and chemical disciplines. You can download ready-to-use models and step-by-step instructions for building the model, and use these as a starting point for your own modeling work. Use the Quick Search to find models relevant to your area of expertise, and login or create a COMSOL Access account that is associated with a valid COMSOL license to download the model files.

Isoelectric Separation

This modeling example applies the Transport of Diluted Species interface to model a separation process. A stream containing six different ionic species is divided into pure component streams by means of migrative transport in an electric field. Free flow electrophoresis can be used to separate macromolecules such as proteins, based on their mobility perpendicular to the flow of the carrier fluid. ...

Determining the Reaction Order from Pressure-Time Data

This model shows how to use the Parameter Estimation feature in the Reaction Engineering interface to find the rate constant and reaction order for the gas phase decomposition of di-tert-butyl-peroxide.

Buoyancy–driven μPCR for DNA Amplification

Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care applications and one strategy that seems very promising is natural convection-based PCR. This model studies ...
