Turbulent kinetic energy dissipation

Short definition of Turbulent kinetic energy dissipation (<math>\varepsilon</math>)
Viscous dissipation rate of turbulent kinetic energy per unit mass

This is the common definition for Turbulent kinetic energy dissipation, but other definitions maybe discussed within the wiki.

The dissipation rate, for short, is main quantity ATOMIX seeks to improve. It is the irreversible rate of dissipation of the turbulence kinetic energy through viscous friction. <math>\varepsilon</math> is related to the sum of variances of the turbulent rate of strain and the rate of shear, and can be approximated using any one component assuming isotropy.
