Kolmogorov length scale
From Atomix
| Short definition of Kolmogorov length scale (Kolmogorov length scale) |
|---|
| Kolmogorov length scale [math]\displaystyle{ L_k }[/math] |
This is the common definition for Kolmogorov length scale, but other definitions maybe discussed within the wiki.
[math]\displaystyle{ L_k=\left(\frac{\nu^3}{\varepsilon}\right)^{1/4} }[/math]
where [math]\displaystyle{ \nu }[/math] is the kinematic viscosity of the fluid and [math]\displaystyle{ \varepsilon }[/math] is the rate of dissipation of turbulence kinetic energy by viscous friction. It is the smallest length scale before viscous effects smoothen the velocity fluctuations.
