2007 X3-Noise Scientific Workshop Lisbon

Experimental, Numerical Analysis and Prediction of Combustion Noise

The 2007 X3-noise Workshop was held on September 27 and 28  at the Instituto Superior Tecnico, Lisbon and it was devoted to  the "Combustion Noise". It coincided also with the11th CEAS Aeroacoustics Committee workshop. There were two keynote lectures and four sections: CFD and CAA techniques, coupling CFD/CAA strategies,source and propagation models and experimental and theoretical methods.
