Fluid Dynamical Process Design

The Fluid Dynamical Process Design group applies mathematical modelling, simulation and optimization to industrial processes which are driven by fluid dynamics. The key expertise lies in the combination of existing tools, like ANSYS Fluent or OpenFOAM, with highly customized models. Through this interplay and the ability to develop application-specific models it becomes possible to represent complex industrial processes on the computer and thus generate a profound understanding. The models are further used in combination with optimization methods for the improvement of the processes.

The competence in the field of flow dynamics covers the entire range of phenomena, from the high turbulent airflow to the flow of non-Newtonian fluids, like polymer melts. Models for the interaction between flow and fine structures - such as particles, fibers or films - are used to simulate cooling, heating or drying processes. Filters and other micro-geometries can be integrated into the simulation of the overall process via a multi-scale approach. Optimization methods are used to determine the best process parameters and shape optimization is used to design flow-optimal components.

Example Projects

 

Temperature Field in a Floodlight

Since their high Luminosity the floodlights of ARRI have a significant heat output. This process is simulated int the project with the help of computer simulations.

 

Melt Flow for Spinning Processes

In different industrial melt spinning processes the plastic granulate is fused in a extruder. We simulate and optimize this process.

 

Analysis and Optimization of a Texturing Nozzle

In machines for the production of carpet fibers, the filaments are first stretched over heated galettes, accelerated subsequently in one or more air shafts by diagonally injected air flows, and finally joined in a lamellar channel for frilling.

 

Simulation-based Design of a Nonwoven Spunbond Plant

A new nonwoven spunbond plant has been constructed on the basis of simulation results.
