Noise reduction is one of the major tasks in todays aircraft development and it is also one of the key goals in the European ACARE 2050 targets, which require the perceived noise level of flying aircraft to be reduced by 65 %. The jet development in the near field is strongly influenced by the larger scales of turbulent motions which are in turn affected by the nozzle geometry and the main wing. The prediction of jet noise sources needs detailed knowledge about the unsteady flow field. In line with this perspective, this thesis analyzes the impact of nozzle interior details and nozzle exit conditions on the flow and the resulting sound field, and the flow field of a complete nozzle-wing geometry to investigate the sensitivity of flow conditions on the jet development.
