Numerical Methods Department

Transonic compressor stage

We develop highly optimised CFD methods for high-fidelity simulation and analysis of turbomachinery components in aircraft engines and stationary gas turbines. As a central component of the virtual engine, advanced numerical methods provide ever deeper insights into real-world flow processes.

Our software is the high fidelity component of the virtual engine

We work on advanced approaches and developments using the CFD simulation suite TRACE (Turbomachinery Research Aerodynamic Computational Environment). TRACE is dedicated to innovative approaches, particularly in the areas of aeroelasticity, aeroacoustics, aerothermodynamics, scale-resolved turbulence and the use of supercomputers. Our aim is to provide an efficient research and design tool for simulation, adapted to the problems of turbomachinery, and to show which modules need to be used for reliable simulation.

The virtual engine is a computer representation of all the geometric and physical properties of an engine. Taking into account all disciplines such as aerodynamics, structural mechanics and thermodynamics, high-fidelity simulations can be used to answer questions about both the individual components and the interaction between all the components of an engine. The holistic view of the engine with all its interactions between systems makes it possible to make engines even more efficient, reliable and environmentally friendly.

Our partners are the national engine and gas turbine industry, which uses TRACE for design, and numerous universities, which use our software for their research activities. We work together in national and international projects on new challenges in the world of simulation.
