Hi
I am trying to reduce the noise from jet thrust in the Turbofan/Turbojet Engine.
1.what type of flow, the hot gases (from the turbine) behaves before existing the Nozzle in the Turbofan/Turbojet Engine?
2.Explain the Flow properties and it's behaviour in the Nozzle

Research...It's not posting questions on boards. If you have more specific questions, please ask away. Do not expect people here to do your grunt work for you.
 
Try a search of jet engine + chevron + noise

A lot of companies have been doing some cool stuff with them lately.
