An Etymological Dictionary of Astronomy and Astrophysics

The distribution of energy over different scales in a → turbulent flow where → energy cascade occurs. Let E be the energy per unit → wave number (k)
and ε the energy → dissipation parameter, E = E(k,ε). → Dimensional analysis yields: E = Cε^2/3k^-5/3, where C is the → Kolmogorov constant.
