Turbulence — 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… … Wikipedia
Magnetohydrodynamic 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… … Wikipedia
Weighing 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… … Wikipedia
Monin-Obukhov Length — The Monin Obukhov Length is the height above ground, where mechanically produced (by vertical shear) turbulence is in balance with the dissipative effect of negative buoyancy, thus where Richardson number equals to 1:L = frac{u^3 *ar heta… … Wikipedia
Turbulent Kinetic Energy — Turbulence Kinetic Energy (TKE) is the mean kinetic energy per unit mass associated with eddies in turbulent flow. It is a concept used to assess what contribution to buoyancy is brought by turbulence.The production of TKE equals the sum of… … Wikipedia
Computational fluid dynamics — Computational physics Numerical analysis … Wikipedia
Renormalization group — In theoretical physics, the renormalization group (RG) refers to a mathematical apparatus that allows systematic investigation of the changes of a physical system as viewed at different distance scales. In particle physics, it reflects the… … Wikipedia
Astronomical seeing — Schematic diagram illustrating how optical wavefronts from a distant star may be perturbed by a layer of turbulent mixing in the atmosphere. The vertical scale of the wavefronts plotted is highly exaggerated. Astronomical seeing refers to the… … Wikipedia
Gas — This article is about the physical properties of gas as a state of matter. For the uses of gases, and other meanings, see Gas (disambiguation). Ga … Wikipedia
Magnetic reconnection — is a physical process in highly conducting plasmas in which the magnetic topology is rearranged and magnetic energy is converted to kinetic energy, thermal energy, and particle acceleration. Magnetic reconnection occurs on timescales intermediate … Wikipedia
Detached eddy simulation — (DES) is a modification of a RANS model in which the model switches to a subgrid scale formulation in regions fine enough for LES calculations. Regions near solid boundaries and where the turbulent length scale is less than the maximum grid… … Wikipedia
