Exhaust mixer

Turbofan engines often feature an exhaust mixer, where the bypass (cold/slow) air is mixed with the core (hot/fast) 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. Additionally, the temperature of the exhaust is reduced, rendering the thermal signature of the aircraft to be lower as well. This attribute is critical in military aircraft where thermal detection or heat-seeking weapons are used.

Ideally, a mixer is also a performance benefit to increasing thrust. The exhaust thrust from a jet engine is equal to exhaust mass flow times exhaust velocity, ie, Thrust=mv, while the energy to make that thrust is given by Energy=(1/2)m(v^2). A mixer helps reduce the fastest exhaust velocities from the core of the engine, while making the average exhaust velocity faster, producing more thrust with the same energy.

Mixer dance

A mixer dance, dance mixer or simply mixer is a kind of participation dance in a social dance setting that involves changing partners as an integral part. Mixing can be built into the dance choreography or can be structured to occur more randomly. Mixers allow dancers to meet new partners and allow beginners to dance with more advanced dancers. Some people may take advantage of mixers to assess dance skills of other persons without fear of being stuck with a poor match for an entire dance.

Some mixer dances have traditional names.

The descriptions of "mixing procedures" vary, however there are several common basic rules.
