scale of turbulence
1Scale analysis (mathematics) — Scale analysis is a powerful tool used in the mathematical sciences for the simplification of equations with many terms. First the approximate magnitude of individual terms in the equations is determined. Then some negligibly small terms may be… …
2Turbulence — In fluid dynamics, turbulence or turbulent flow is a fluid regime characterized by chaotic, stochastic property changes. This includes low momentum diffusion, high momentum convection, and rapid variation of pressure and velocity in space and… …
3turbulence — i. The short period and small scale oscillations in fluid flow. ii. A state of fluid flow in which the instantaneous velocities exhibit irregular and apparently random fluctuations so that in practice only its statistical properties can be… …
4Magnetohydrodynamic turbulence — Magnetohydrodynamics (MHD) deals with what is a quasi neutral fluid with very high conductivity. The fluid approximation implies that the we focus at macro length and time scales which are much larger than the collision length and collision time… …
5atmospheric turbulence — ▪ meteorology small scale, irregular air motions characterized by winds that vary in speed and direction. Turbulence is important because it mixes and churns the atmosphere and causes water vapour, smoke, and other substances, as well as… …
6clear-air turbulence — /klear air / atmospheric turbulence, sometimes severe, occurring in air devoid of clouds or other visible indicators that turbulence might be present. Abbr.: CAT [1950 55] * * * ▪ atmospheric science erratic air currents that occur in… …
7Weighing scale — Emperor Jahangir (reign 1605 1627) weighing his son Shah Jahan on a weighing scale by artist Manohar (AD 1615, Mughal dynasty, India). A weighing scale (usually just scales in UK and Australian English, weighing machine in south Asian English or… …
8Procedural texture — A procedural texture is a computer generated image created using an algorithm intended to create a realistic representation of natural elements such as wood, marble, granite, metal, stone, and others.Usually, the natural look of the rendered… …
9Magnetohydrodynamics — For the academic journal, see Magnetohydrodynamics (journal). Magnetohydrodynamics (MHD) (magneto fluid dynamics or hydromagnetics) is an academic discipline which studies the dynamics of electrically conducting fluids. Examples of such fluids… …
10Potential temperature — The potential temperature of a parcel of fluid at pressure P is the temperature that the parcel would acquire if adiabatically brought to a standard reference pressure P {0}, usually 1000 millibars. The potential temperature is denoted heta and,… …
