Turbulence dissipation, \epsilon is the rate at which turbulence kinetic energy is converted into thermal internal energy. The SI unit of \epsilon is J / kg s = m^2 / s^3.

\epsilon \, \overset{\underset{\mathrm{def}}{}}{=} \, nu \overline{\frac{\partial u_i'}{\partial x_k}\frac{\partial u_i'}{\partial x_k}}
