instability
51instability line — Meteorol. a nonfrontal line of convective activity in the atmosphere, usually several hundred miles long but of relatively brief duration …
52Electrothermal instability — NOTOC The electrothermal instability (also known as the ionization instability or Velikhov instability in the literature) is a magnetohydrodynamic (MHD) instability appearing in magnetized non thermal plasmas used in MHD converters. It was first… …
53Rayleigh–Taylor instability — The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), is an instability of an interface between two fluids of different densities, which occurs when the lighter fluid is pushing the heavier fluid. [citation… …
54Kelvin–Helmholtz instability — Numerical simulation of a temporal Kelvin–Helmholtz instability The Kelvin–Helmholtz instability, after Lord Kelvin and Hermann von Helmholtz, can occur when velocity shear is present within a continuous fluid, or when there is sufficient… …
55Pair-instability supernova — A pair instability supernova occurs when pair production, the production of free electrons and positrons in the collision between atomic nuclei and energetic gamma rays, reduces thermal pressure inside a supermassive star s core. This pressure… …
56Richtmyer-Meshkov instability — The Richtmyer Meshkov instability (RMI) occurs when an interface between fluids of differing density is impulsively accelerated, e.g. by the passage of a shock wave. The development of the instability begins with small amplitude perturbations… …
57Magnetorotational instability — The magnetorotational instability or MRI is a fluid instability that arises when the angular velocity of a magnetized fluid decreases as the distance from the rotation center increases. It can also be known as the Velikhov Chandrasekhar… …
58Modulational instability — In the field of nonlinear optics, modulational instability is a phenomenon whereby deviations from an optical waveform are reinforced by nonlinearity, leading to the generation of spectral sidebands and the eventual breakup of the waveform into a …
59Crow Instability — The Crow instability is responsible for the shape of this contrail …
60Plateau-Rayleigh instability — The Plateau Rayleigh instability, often just called the Rayleigh instability , explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor… …
