turbulence length scale for airfoil - 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.
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%).
2 апр. 2021 г. · For example, at the inlet to a turbine stage a typical turbulence length scale could be say 5% of the channel height. When the inlet flow is ...
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.
17 сент. 2010 г. · However, it can be reasonably argued that the turbulence integral length scale can affect the performance of an airfoil in free-stream.
Very high-quality wind-tunnels can also reach low turbulence levels, typically below 1.0%.
