81GIRD — Russian Group of Study of Reactive Motion (in Russian: Группа изучения реактивного движения (ГИРД), transliterated GIRD) was a Soviet research bureau founded in 1931 to study various aspects of rocketry, which was later incorporated into the… …
82Prandtl-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… …
83Free molecular flow — describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test. For tubes/objects of the size of several cm, these means pressures well below 10 3 torr. This is… …

89atomic physics — Scientific study of the structure of the atom, its energy states, and its interaction with other particles and fields. The modern understanding of the atom is that it consists of a heavy nucleus of positive charge surrounded by a cloud of light,… …
90Rankine–Hugoniot equation — The Rankine–Hugoniot equation governs the behaviour of shock waves normal to the oncoming flow. It is named after physicists William John Macquorn Rankine and Pierre Henri Hugoniot, French engineer, 1851 1887.The idea is to consider one… …
