The feedback forces exerted by particles suspended in a turbulent flow is shown to lead to a new scaling law for velocity fluctuations associated to a power-spectra $\propto k^{-2}$. The mechanism at play relies on a direct transfer of kinetic energy to small scales through Kelvin--Helmholtz instabilities occurring in regions of high particle density contrast. This finding is confirmed by two-dimensional direct numerical simulations.

The significance of two-way coupling in two-dimensional, dusty turbulence
In 2D dusty turbulence, two-way coupling enhances vorticity intermittency and produces non-trivial scale-invariance in structure functions, which is captured by modeling particle feedback as spatially localized small-...
