• 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

• Oblique shock — A small scale X 15 placed in a NASA supersonic wind tunnel produces an oblique shock wave at the nose of the model (along with other shocks). An oblique shock wave, unlike a normal shock, is inclined with respect to the incident upstream flow… …   Wikipedia

• Blast wave — A blast wave in fluid dynamics is the pressure and flow resulting from the deposition of a large amount of energy in a small very localised volume. The flow field can be approximated as a lead shock wave, followed by a self similar subsonic flow… …   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

• 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

• 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 …   Aviation dictionary
