Kolmogorov length scale

(Kolmogorov length scale)| }}
Kolmogorov length scale <math>L_k</math>

This is the common definition for Kolmogorov length scale, but other definitions maybe discussed within the wiki.

{{#default_form:DefineConcept}} {{#arraymap:|,|x||}}

<math>L_k=\left(\frac{\nu^3}{\varepsilon}\right)^{1/4}</math> where <math>\nu</math> is the kinematic viscosity of the fluid and <math>\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.
