The smallest length scale before viscous effects smooth the velocity fluctuations.
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.
