Research - Applied Supercomputing in Engineering

The focus of our group is on simulations of large technical applications, in particular in the field of fluid dynmaics. The main research topics are multi-physics and multi-scale problems as well as the efficient realization of such problems on high performance computers.

Coupled Multi-Scale Simulation


Multi-scale applications typically are characterized by regimes of different physical properties, which require individual numerical handling of each of them. In aero-acoustics e.g. very small structures with high energy need to be resolved in a spatially limited domain, but at the same time the sound wave propagation needs to be simulated across long distances.

Computational Analysis and Optimization of Real Gas Flows


Industrial applications require the simulation of real gas flow. We work on the real-gas extension of a highly local Discontinous Galerkin LES-solver and its HPC optimization for the simulation of automotive gas injection problems.

Aero-Acoustic Simulations of Flow through Porous Media


The Lattice Boltzmann Method is used to investigate aeroacoustic phenomena driven by air flow through a porous media silencer. The goal is to achieve optimizations for the acoustic and flow properties of the silencer.

Medical Physics Application


 Cardiovascular disease annually claims the lives of approximately 17 million people worldwide. A particular challenge is the rupture risk assessment of cerebral aneurysm in order to support the treatment planning for clinicians. In this context, transient blood-flow simulation in patient specific geometries, acquired from CT-data, is performed.

Rarefied Plasma Flows


In engineering applications such as electric space propulsion and high power microwave generators rarefied plasma flows occur where the continuum assumption fails. Therefore, the simulation has to take the movement of discrete particles into account. We apply a Particle-in-Cell (PIC) scheme, extended by electromagnetic interactions between charged particles as well as neutral particles.
