How Does Fluid Flow in Nozzles Impact Jet Engine Noise?

AI Thread Summary
Fluid flow in nozzles significantly influences jet engine noise, particularly in Turbofan and Turbojet engines. The hot gases from the turbine exhibit complex flow behaviors as they exit the nozzle, affecting both thrust and noise levels. Key flow properties include velocity, temperature, and pressure, which can be manipulated to reduce noise. Recent innovations, such as chevron designs, have shown promise in mitigating jet thrust noise. Understanding these dynamics is crucial for effective noise reduction strategies in jet engines.

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

Try a search of jet engine + chevron + noise

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

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
