Batchelor scale
text:
In fluid and molecular dynamics, the Batchelor scale, determined by George Batchelor (1959), describes the size of a droplet of fluid that will diffuse in the same time it takes the energy in an eddy of size η to dissipate. The Batchelor scale can be determined by: where: η = 1 / 4 is the Kolmogorov length scale.
Sc is the Schmidt number.
ν is the kinematic viscosity.
D is the mass diffusivity.
ε is the rate of dissipation of turbulence kinetic energy per unit mass. Similar to the Kolmogorov mic
