ABSTRACT
In this chapter, the flow is assumed to be adiabatic and inviscid with a constant cross-sectional area, and the gas is thermally and calorically perfect. This type of flow occurs in shock tubes, internal ballistics, and generally inside ducts, such as the flexible tubes of a stethoscope. Our presentation emphasizes physical and mathematical aspects, although applications such as internal ballistics are treated. Other applications of unsteady, one-dimensional flow, such as pressure exchangers, pulse combustors, and ejectors, can be fgound in the books by Azoury (1992), Kentfield (1993), and Weber (1995).
