Batchelor scale

The Batchelor scale, determined by George Batchelor (1954), describes the size of a droplet of scalar 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: * is the Kolmogorov length scale. * is the Schmidt number. * is the kinematic viscosity. * is the mass diffusivity. * is the rate of dissipation of turbulent kinetic energy per unit mass.
