In fluid dynamics, an N-wave refers to a finite-amplitude traveling wave in which a compression wave is followed by a rarefaction (or expansion wave).[1] In the inviscid limit, the N-wave consists of two shock waves, namely a compression shock wave, followed a rarefaction shock wave; a rarefaction shock wave on its own is not possible, except some special cases.[2][3][4]
