This chapter investigates one-dimensional, compressible, inviscid flow. Flow is said to
be one-dimensional when the fluid properties only depend on a single Cartesian coordinate.
Flow
is said to be compressible when there is a significant variation in the
mass density along a given streamline. Generally speaking, compressible
flow is much more common in gases than in liquids. As described in
Section 1.17, subsonic gas dynamics (i.e., dynamics in
which the typical flow speed is much less than the propagation speed of
sound waves in the gas) is essentially incompressible, and is governed by the
same equations that govern the incompressible flow of liquids. On the other hand,
sonic gas dynamics (i.e., dynamics in
which the typical flow speed is comparable with the sound speed) exhibits
significant differences to subsonic dynamics. Hence, this chapter
will concentrate on sonic gas dynamics. More information on
this subject can be found in Liepmann & Roshko 1957, Hughes & Brighton 1999, and
Milne-Thomson 2011.
