Jet exhaust aerodynamics and noise (JEAN)

Objective

The JEAN proposal will address the prediction of noise by jet flows including the effects of mixing enhancement and co-axial configurations CFD techniques will be applied and validated to predict the turbulence characteristics of jets. These will be coupled to noise source generation and propagation models to estimate the near and far field noise. The results will be critically evaluated against data obtained from a series of carefully designed experiments. The validated noise prediction procedures will be applied to mixing enhancement and to co-axial jets and the results compared with existing high quality data for these configurations. The work will recommend the use of a particular suite of techniques which will have been validated for specific applications. These will then provide the basis for the development valuation tools for new concepts in low noise design of jet engines.
