Filters, such as those installed in automobiles, for example, have to meet increasingly stringent requirements. At the same time, the products are expected to become more and more market-ready.

Filtration and Separation

The area "Filtration and Separation" is devoted to the development of specialized mathematical models, algorithms and simulation techniques for the computer-aided study and optimization of separation processes. In particular, our activities include filter media and filter elements, adsorption, reactive flows, fractionation and the coupling of CFD and structural mechanics simulations.

Many results of our research and developments are bundled in own software developments, e.g. the simulation tools FiltEST and PoreChem. Futhermore, we offer simulation services and consulting.

 

Example Projects

 

Simulation of Diesel Particulate Filter

Fraunhofer ITWM cooperates with Robert Bosch GmbH to develop innovative particle filtering systems for the exhaust gas system of diesel vehicles.

 

Dimensioning of Pleated Filters

A pleated filter contains a folded filter medium to maximize the effective filter surface.The goal of the project is to establish a relation between various aspects.

 

Nano Meltblown Fibers

The project NaBlo aims to reduce the exposure to fine dust particles by new filter systems based on nano fiber meltblown media. 

 

Deformation of filter media

We have been working on the adequate modeling and simulation of the deformation of filter materials for many years.

 

Simulation of asymmetrical Flow Field-Flow Fractionation

Separation of nano- and microparticles in solutions and dispersions.

 

Analysis and Optimization of Paper Machine Clothings

The behaviour of press felts is analyzed and simulated at the Fraunhofer ITWM.
