Abstract

In the frame of the DLR project SAMURAI, the German Aerospace Center performed an engine ground test with an installed IAE V2527, which was accompanied by various CFD studies. One of these studies aimed at simulating the experimental set-up, including aircraft, ground and hangar with a RANS approach. Therefore, the two equation eddy viscosity model Menter SST and the Reynolds stress model SSG/LRR-g were utilized. The scope of this paper is to illustrate the numerical approach and results of this simulation. Numerical results from the jet flow were compared with measured data obtained using both a Particle Image Velocimetry and Backward Oriented Schlieren method. Regarding the velocity distributions within the outer jet shear layer, the comparison with particle image velocimetry data showed good agreement especially for the Menter SST turbulence model. However, the turbulent kinetic energy was generally overpredicted in the CFD results.
