Our competence covers most parts of the wide field of fluid dynamics. Being typically described by means of the Navier-Stokes equations, we deal with a huge spectrum of associated identification numbers, such as reynolds- or mach numbers and various material models as well. In many cases fluid structur interaction or heat radiation must be incorporated. For many problems we worked out our own specific models. Being based on methods of model reduction they allow for a representation of reality which is more efficient and accurate at the same time. According to this, we use a good deal of own software in addition to standard tools like FLUENT or CFX. For the simulation of rarified gases (Boltzman equations) own software is available too.

Projects

• Optimal Control of Melt Flow for Spinning Processes

  

  During different industrial melt spinning processes, polymer resin is melted in an extruder and flows to the individual capillaries of a spinning head via a distributor. Generally, the cross-section of the polymer melt flow must be expanded from that of the inflow tube to the considerably larger cross-section of the spinning plate with its capillaries.

• Temperature field in a floodlight

  

  The company ARRI Lichttechnik is a worldwide leading producer of lighting equipment for, e.g., studio technology and motion-picture production. The floodlights produced by the company ARRI provide a significant thermal output due to their strong luminosity.

• 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.
