Numerical flow simulation (CFD) is mainly used at the Institute of Jet Propulsion to investigate complex flow processes in turbomachinery components. Great importance is attributed to the mutual complementation of experimental measurement data and numerical simulations and the resulting synergy effects. Thus, experimental data can be used to validate numerical simulations. In turn, high-resolution flow simulations provide valuable additional information in flow regions that are difficult to access experimentally.

Test Stand Aerodynamics
The engine test facility operated at the Institute of Jet Propulsion features complex internal aerodynamics. For the development of new test vehicles, a numerical model is used which allows the special flow guidance to be predicted and taken into account.
Complex Intake Geometries
Intake disturbances, as they occur in highly bent intake geometries, play a major role in compressor aerodynamics. At the Institute of Jet Propulsion, transient coupled calculations of highly bent intake ducts in combination with multistage low-pressure compressors are carried out in parallel with the experimental investigations at the engine test facility. This places high demands on the computational methods used and requires very high computational effort. However, it enables extended insights into the highly complex aerodynamics, which remain hidden in the experimental investigations.
