New Test Device for Porous Media

Departmental lab is home to a new air permeability test apparatus. We are now able to determine the permeability of a wide spectrum of porous materials (for example, nonwoven fabrics,
weaves, knits, crochets, foams) because of the device’s large measuring range. In future combination with the existing DMTA (dynamic-mechanic-thermal analysis) test unit, material characterizations with flow and structural mechanics will be possible from a single source. In particular, it enables us to investigate the relationships between mechanical deformation and the associated changes in flow resistance.

Integration Project – Digitalization of Terahertz Technology

We focus on the experimental qualification of microstructures within the framework of an integration project with the Center for Materials Characterization and Testing (MC). It serves to expand the business areas and promote long term cooperation.

Numerical models and their advanced development are validated on the basis of experimental results to review forecasting reliability. We use the computer to create an optimal microstructure based on the desired material properties, for example, a certain permeability within a specified stiffness.

A 3D-printer creates an exact copy of this computer model with (sub-) micrometer resolution, which is then tested for the desired properties. Until now, only indirect verification of microstructure simulations was possible. The success of our explicit validation of additive microstructures creates customer trust and promises new markets.

Reliably Simulating Polyurethane Foams

Car seats, mattresses and insulation materials are often made of polyurethane foams.


Scientific Staff, Project Manager, Software Developer

If you are interested in solving interesting, up-to-date modeling and simulation tasks for complex technical-scientific questions in the industrial environment, you should contact us.

In current projects with the industry, we are concerned with the flow-dynamic design of filter materials and filter systems, the simulation-based development of fuel cell and battery materials and the thermomechanical behavior of modern composite and hybrid materials.

They work on the latest developments in the efficient numerical treatment of multiscale models for the virtual design of materials and products and can contribute to the development of user-friendly simulation tools.

From all applicants, we expect confident handling of modern programming languages, preferably C ++, interest or experience in software development and object-oriented software design as well as good German and English language skills.


Graduate Assistant

The department »Flow and Materials Simulation« provides interesting tasks for scientific assistants from the main study course in mathematics, engineering sciences or physics. Expect basic knowledge and interest in computational simulation and / or programming competency.
