Prandtl-Meyer expansion fan — A Prandtl Meyer expansion fan is a centered expansion process, which turns a supersonic flow around a convex corner. The fan consists of infinite number of Mach waves, diverging from a sharp corner. In case of a smooth corner, these waves can be… … Wikipedia
Prandtl-Meyer function — describes the angle through which a flow can turn isentropically for the given initial and final Mach number. It is the maximum angle through which a sonic (M = 1) flow can be turned around a convex corner. For an ideal gas, it is expressed as… … Wikipedia

Rarefaction — is the reduction of a medium s density, or the opposite of compression. A natural example of this is as a phase in a sound wave or phonon. Half of a sound wave is made up of the compression of the medium, and the other half is the decompression… … Wikipedia
Mach wave — In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach… … Wikipedia
Bow shock (aerodynamics) — For other uses, see Bow shock. A blunt body fired from a gun against a supersonic flow in a wind tunnel, producing a bow shock. A bow shock, also called a detached shock, is a curved, stationary shock wave that is found in supersonic flow past a… … Wikipedia
Moving shock — In fluid dynamics, a moving shock is a shock wave that is traveling through a fluid (often gaseous) medium with a velocity relative to the velocity of the fluid already making up the medium.[1] As such, the normal shock relations require… … Wikipedia
