Filtration, Separation and Reactive Transport

The optimization of products and processes in separation technology and chemical reaction engineering (e.g. filter devices, fixed bed reactors) is challenging, among other reasons because the fluid flow and the physical/chemical processes interact with each other at various length scales. To assist scientists and engineers in their work, we offer problem-adapted simulation software, services and consulting in the following fields:

• Filtration
• Separation
• Reactive Transport

FiltEST (Filter Element Simulation Tool) is a ready-to-use simulation software for filtration. Users can create digital twins of multilayered filter media, filter pleats and entire filter elements to study their performance in terms of efficiency, lifetime, and dust holding capacity. 

In addition, we offer services for the computer-aided optimization of pleated filters with regard to pressure drop and service life. 

In more and more fields of application, the deformation of filter media during operation is not negligible. For such cases, we develop models and coupled simulation methods for the Fluid-Porous-Structure Interaction (FPSI). In addition, our simulations can take into account the impact of the compression of the nonwoven material during manufacturing (e.g. due to the pleating process) on filter performance and lifetime.

For a more reliable prediction of the protection level provided by filtering facepieces, we have intensified our research and development activities on the computer-aided prediction of the aerosol dispersion for typical indoor scenarios. Furthermore, we create computer models for the entire process chain from nonwoven production to the final product, such that quality and availability of personal protection equipment can be improved.
