adiabatic efficiency

Ok cool down you nerds!

Saw this word adiabatic in a magna charger add for a screw compressor. so I check out what it meant (me no likey words ununderstandable ) and this page was filled with some interesting tid bits people may want to take a look at. http://www.engineersedge.com/thermodynamics.htm
just sharing...
Well ok now im wondering what the efficiency of our turbos are?

I learned what that term means in physics last semester. Adiabatic is actually a general term describing a process where gas expands and cools or compresses and heats up without loosing or gaining any heat to/from the surroundings.

Do a search on the Carnot Engine/Cycle. If you think this sort of stuff is cool, you can learn a lot about thermodynamics just by understanding the principals of this theoretical engine.

The late great Smokey Yunick spoke of it but I don't understand it much unless the little slow turning hot air engine toy I saw that actually runs from the heat of your hand at a steam/antique tractor show has anything to do with it.

Adiabatic heating refers to heating without a heat source such as heat generated by pressure. Diesel engines rely on adiabatic heating during their compression stroke to reach the high temperatures needed to ignite the fuel.
Adiabatic heating also takes place when your turbo compresses air.

There is also adiabatic cooling, most often seen by pressure release. Example is air cooler than the tire coming out when you let air out or an air tool's exhaust outlet icing up even when it's above freezing.
