Abstract

The present work concerns the numerical prediction of jet-wing interaction noise for the geometry specified in the European project JERONIMO, which consists of an (U)ltra (H)igh (B)ypass (R)atio (UHBR) nozzle mounted in close proximity to a swept wing with deployed flap (dF=14°). The geometrical setup provides a realistic scenario for a modern aircraft at 1:10 model scale but slightly reduced complexity neglecting details such as pylon, struts and slat. Results are obtained using a newly extended block structured mesh that resolves the high-lift wing with the UHBR nozzle and applying the latest version of the Forced Eddy Simulation approach based on a combined active/dissipative subgrid scale model. In agreement with experiment, the jet flow interacts with the trailing edge and generates additional installation noise, which predominates the low frequency part of the acoustic spectrum.
