Jet Noise

Overview of Jet Noise Research

 

Our goals in this research are to answer fundamental questions on jet noise and its control. For example:

  • What is the relation between coherent structures in the flow and noise?
  • How does the jet filter turbulent distrubances to generated fluctuations in the near acoustic field?
  • What is the nature of hydrodynamic and acoustic fluctuations in the near acoustic field?
  • How exactly do active control techiniques based on small perturbations influence noise generation?

We employ experimental data extensively to ensure that our simulations represent reality. The validated simulations are then post-processed with sophisticated statistical techniques to generate enabling insight. Some of our recent work may be viewed with the links on the left.
