Industrialists and government agencies have praised the technological effect prediction quality of ONERA's aerodynamic simulation software elsA. The latest developments around the multigrid method Chimère have been due to the complexity and details in regard to turbomachinery... The presence of technological effects and innovating technologies in sizes that are much smaller than the characteristic dimensions of the general flow make the modeling even more difficult
Great progress has been achieved in noise reduction of the engines over the past decades, so the aerodynamic noise is not negligible anymore, particularly in landing configuration... Acoustic propagation around a high lift wing profile in a non- uniform flow. In this domain, a deep understanding of the origins of aerodynamic noise is required to produce efficient control devices
