Subsonic and supersonic jet noise predictions from statistical source models

摘要

Subsonic and supersonic jet noise is determined numerically from statistical source models. The goal is to develop prediction methods for high-speed jet noise for application to aeronautical and space transportation systems. In this framework, a combination of a k-∈ turbulence closure with an acoustic analogy provides an interesting way to compute such radiated acoustic fields. Three acoustic analogies are investigated.
