DANTE - Development of Aero-vibro-acoustics Numerical and Technical Expertise

Obiettivo

The DANTE project aims to strengthen and expand the skills of the Computational Acoustics Laboratory in aero-vibro-acoustics through the development of an integrated software including both new methods, which are under development, and other ones already mature. More specifically, the project has the following objectives :

  • to develop and implement FMM ( Fast Multipole Method) algorithms to reduce computational time and RAM usage of BEM methods;
  • to model acoustic sources for aeroacoustic analysis from CFD-RANS solutions;
  • to model boundary conditions for vibro-acoustic analysis ;
  • to build up an integrated software for multi-domain analyses that includes methods for the treatment of aero-vibro-acoustic sources and FEM/BEM/integral propagation algorithms with high-performance computing potential.

DANTE
Environmental Impact of Air Transport
This project aims to strengthen and expand the skills and capabilities in computational aero-vibro-acoustic. DANTE objective is, on one side, to increase the competitiveness of CIRA and, on the other side, to extend the use of current aero-vibroacoustic tools in industrially relevant applications.
