In aviation, an exhaust mixer or flow mixer is a feature of many turbofan engines, where slower, colder bypass air is mixed with faster, hotter core exhaust gases, before exhausting to atmospheric pressure through a common (mixed flow) propelling nozzle. == Benefits == The mixer reduces the velocity of the core exiting air, and consequently, reducing the amount of noise produced.
