As part of a more global research effort towards a greener aviation, the present study
focuses on the noise impact by aircraft operations around a major airport, namely the Hong …

Product improvement, usually through changes in design and functionality, is relying more
and more on the continuous analysis of large amounts of data. Product data can come from …

In acoustic emission tests, the effective signal generated by crack initiation and propagation
inside a sample is easily affected by the testing machine, earth vibration and other external …

The present article proposes an advanced methodology for numerically simulating complex
noise problems. More precisely, we consider the so-called multi-stage acoustic hybrid …

Ultra-high bypass ratio (UHBR) engines are designed as compact as possible and are
characterized by a short asymmetric air inlet and heterogeneous outlet guide vanes (OGVs) …

Severely calcified plaque is of great concern when planning and implementing a stenting
intervention. In this work, computational models were developed to investigate the influence …

The present article concerns a commonly used methodology for the numerical simulation of
acoustic emission and propagation phenomena. We consider the so‐called multi‐stage …

With the objective of aircraft noise mitigation, we here address the numerical
