Abstract
As the bypass-ratio of aeroengines continues to grow, the extra noise generated by the interaction of the jet with the wings becomes more relevant. Understanding the underlying mechanisms of noise generation and predicting the far-field noise of this type of configurations is therefore important for the development of the next-generation ultra-high-bypass-ratio engines. In this paper, a two-step LES/APE coupled framework has been applied to investigate these effects on a simplified configuration. The flow and acoustic results are compared to experimental data measurements available in the literature, achieving a good agreement. The installation effects and sound sources are also studied by analyzing the near-field of the LES/APE simulations.
期刊介绍：
Flow, Turbulence and Combustion provides a global forum for the publication of original and innovative research results that contribute to the solution of fundamental and applied problems encountered in single-phase, multi-phase and reacting flows, in both idealized and real systems. The scope of coverage encompasses topics in fluid dynamics, scalar transport, multi-physics interactions and flow control. From time to time the journal publishes Special or Theme Issues featuring invited articles.
Contributions may report research that falls within the broad spectrum of analytical, computational and experimental methods. This includes research conducted in academia, industry and a variety of environmental and geophysical sectors. Turbulence, transition and associated phenomena are expected to play a significant role in the majority of studies reported, although non-turbulent flows, typical of those in micro-devices, would be regarded as falling within the scope covered. The emphasis is on originality, timeliness, quality and thematic fit, as exemplified by the title of the journal and the qualifications described above. Relevance to real-world problems and industrial applications are regarded as strengths.
