supersonic flow
51shock wave — n. 1. a surface of discontinuity in a flow of air, sound, etc. set up when the flow suddenly changes from subsonic to supersonic, characterized by marked increases in temperature, pressure, and density of the flow, as in supersonic flow about an… …
52Computational Aeroacoustics — While the discipline of Aeroacoustics is definitely dated back to the first publication of Sir James Lighthill[1][2] in the early 1950s, the origin of Computational Aeroacoustics can only very likely be dated back to the middle of the 1980s.… …
53Viscosity — For other uses, see Viscosity (disambiguation). Viscosity The substance above has lower viscosity than the substance below SI symbol: μ, η SI unit: Pa·s  …
54shock wave — An area or sheet of discontinuity (i.e., of abrupt changes in conditions) set up in a supersonic field of flow, through which the fluid undergoes a finite decrease in velocity accompanied by a marked increase in pressure, density, temperature,… …
55Stagnation pressure — In fluid dynamics, stagnation pressure is the pressure at a stagnation point in a fluid flow, where the kinetic energy is converted into pressure energy. It is the sum of the dynamic pressure and static pressure at the stagnation point. [… …

58Chemical oxygen iodine laser — Chemical oxygen iodine laser, or COIL, is an infrared chemical laser. As the beam is infrared, it cannot be seen with the naked eye. It is capable of output power scaling up to megawatts in continuous mode[citation needed]. Its output wavelength… …
59CENBOL — or CENtrifugal pressure supported BOundary Layer refers to the region of an accretion flow around a black hole. The basic idea is that since the centrifugal force l2/r3 increases very rapidly compared to the gravitational force (which goes as… …
