「ノズル」の版間の差分

===高速度ノズル===

一般に、ノズルは[[内部エネルギー]]を犠牲にする代わり、[[運動エネルギー]]を増加させる事に用いられる。

 

Nozzles can be described as ''convergent'' (narrowing down from a wide diameter to a smaller diameter in the direction of the flow) or ''divergent'' (expanding from a smaller diameter to a larger one). A [[de Laval nozzle]] has a convergent section followed by a divergent section and is often called a convergent-divergent nozzle.
