Predicting the noise produced by turbo machines requires three essential modelling components:

1. an accurate description of the flow through the turbo machine (WP1)
2. a model predicting the amplitude of the acoustic source from the results of the CFD calculation (WP2)
3. a prediction of the propagation of the source in a lined duct taking into account the flow field in the duct (WP3)

The different components must then be seamlessly integrated and connected to an optimisation tool (WP4).
Finally each component of the loop and the integrated system must be validated against experimental results (WP5)
In order to be successful the project must be managed and its results disseminated and exploited (WP6).
The proposal is a result of the SCRATCH initiative and gives therefore a leading role to SMEs. The focus is also on the development of a product methodology that can be exploited by the SMEs at the end of the project.
