turbulent length scale - Axtarish в Google
15 июн. 2012 г. · The turbulence length scale, l , is a physical quantity describing the size of the large energy-containing eddies in a turbulent flow.
In fluid dynamics, the Taylor microscale, which is sometimes called the turbulence length scale, is a length scale used to characterize a turbulent fluid flow.
Good wind tunnels can produce values as low as 5·10−4 (0.05%). Fully turbulent flows usually have intensities between 0.05 (5%) and 0.1 (10%).
The turbulent length scale, l , for the definition of the turbulent eddy viscosity, is a function of the rate of dissipation of turbulent kinetic energy.
The smallest length scales existing in a turbulent flow are those where the kinetic energy is dissipated into heat. For very high Reynolds number flows, the ...
18 июн. 2008 г. · We formulate a general length scale equation, which encompasses all current approaches. This equation is devoid of inconsistencies and should ...
The integral length scale, Ȧ௫ (macro-scale), is a measure of the largest eddy size in the turbulent fluid and is calculated using the method shown by Roach ...
The tur- bulence length scale corresponds to the “energy-containing sub-range” of turbulent velocity fluctuations associated with the peak of the streamwise ...
