Understanding the cascading process of turbulent kinetic energy from large-scale fluid motions to small-scale and lesser-scale fluid motions is critical to modeling strategies for geophysical and industrial flows. The phenomenological explanation of the transfer of energy across scales was introduced in the classical paper by Kolmogorov [1], but the concept of a turbulent cascade in terms of interactions among eddies was proposed earlier by Richardson [2] and later by Obukhov [3]. Since then, many detailed investigations, mostly in isotropic turbulence, have greatly advanced our understanding of high-Reynolds-number turbulent flows.
