Some modern-day turbofan engines employ chevrons (sawtooth pattern or serrated edges) at the back of their fan housings and exhaust nozzles essentially to reduce jet noise emanating from separated-flow engines. Aside the reduction of acoustic level of the exhaust gases, other technical benefits may accrue from the introduction of such mixing devices. From point of view of a researcher/industrialist, what are other technical benefits of chevrons' installation in the exhaust nozzles of a modern turbofan engine?
I don´t know if the chevrons have this purpose here, but these devices also are used to separate the droplets of liquid mixed in a stream of gas or steam.
When the stream impacts on the chevrons, they collect the droplets.
Emilio Casado Thanks for your timely and insightful comment. It is well appreciated.
Chevron nozzles aid in reducing pressure variation and, as a result, jet noise. The chevron nozzle minimizes jet noise by influencing how air mixes after passing through and around the engine.
