compression wave

[kəm′presh·ən ‚wāv]

(fluid mechanics)

A wave in a fluid in which a compression is propagated.

compression wave

A shock wave that forms on the surface of an airfoil moving through the air at supersonic speeds. The reverse phenomenon is an expansion wave. Also called bow wave. See also bow shock wave and expansion wave.
