The current development of modern aircraft concepts often focuses on fully integrated propulsion system. These fully integrated propulsion systems require the use of short highly bent intake ducts. At the Institute of Jet Propulsion a short highly bent intake duct, the military Engine Intake Research Dicht (MEIRD), was designed and developed. Teh MEIRD was investigated experimentally as well as with steady state RANS simolations with many different numerical setup parameters. From this extensive study, one setup was chosen for detailed investigations. To ensure the validity of the predicted flow phenomena inside the MEIRD, the results were compared with experimented data, gained at the Institute's jet engine test facility. It is shown that good qualitative and quantitative data can be achieved using a proper numerical setup.    «
