Angebotene Bachelorarbeiten:
any timeTopics in computational aeroacoustics

Within our multiphysics simulation framework ZFS, we have a solver for computational aeroacoustics. Here we follow a hybrid approach to acoustics simulation: first, the flow field is obtained with our flow solver. Second, acoustic source terms are extracted, which are then used in our acoustics solver that uses the acoustic perturbation equations. If you are interested, please let me know - usually it is possible to find a topic that suits your ideas and our needs at the same time.

any timeTopics in discontinuous Galerkin methods

Our multiphysics simulation framework ZFS has a built-in solver based on the discontinuous Galerkin method (c.f. my talk). On this solver there are numerous opportunities for Bachelor/Master theses or Projektarbeiten. If you are interested, please let me know - usually it is possible to find a topic that suits your ideas and our needs at the same time.

Angebotene HiWi-Jobs:
Development of a hybrid flow-aeroacoustics solver

Most current research problems in the field of computational fluid dynamics (CFD) require the use of supercomputing facilities (>100k processors) to obtain accurate results within reasonable time frames. At the Institute of Aerodynamics we have developed a massively parallel simulation framework, which is used to problems in fluid dynamics, combustion and aeroacoustics. We are looking for a student assistant at the next possible date to further improve our solver. The focus is on code development, discontinuous Galerkin methods, and aeroacoustics simulations.

Parallel visualization of large datasetsInfoblatt herunterladen

At the Institute of Aerodynamics we have developed a massively parallel simulation framework, which is used to simulate fluid dynamics, combustion and aeroacoustics on hierarchical Cartesian grids. The datasets from these simulations often exceed 50-100 GB in size, which presents unique difficulties when attempting to visualize them. We are looking for a student assistant at the next possible date to further develop our parallel visualization plugin for hierarchical meshes in ParaView.
