Energy cascade

Flow visualization of a turbulent jet, made by laser-induced fluorescence. The jet exhibits a wide range of length scales, a prerequisite for the appearance of an energy cascade in the turbulence modelling.

In continuum mechanics, an energy cascade refers to the transfer of energy from large scales of motion to the small scales – called a direct energy cascade. Or a transfer of energy from the small scales to the large scales – called an inverse energy cascade. This transfer of energy between different scales requires that the dynamics of the system is nonlinear.
