Abstract
Prediction of the noise from impinging turbulent, hot, supersonic jets from real flight systems in an operational environment is an extremely challenging problem. The broad ranges of both temporal and spatial scales that affect the results make a conventional large eddy simulation impractical. To address this issue, a technique is proposed which makes use of localized high-fidelity simulations, while taking into account the conditions in the wider domain. In this manner, practical solutions for jet impingement problems involving full-scale flight hardware can be obtained.
