Interface-induced turbulence in viscous binary fluid mixtures
We uncover interface-induced turbulence, a striking nonequilibrium statistically steady state with spatiotemporal chaos, emerging from interfacial fluctuations in low-Reynolds-number binary-fluid mixtures. Using direct numerical simulations of the Cahn-Hilliard-Navier-Stokes equations, we reveal a power-law energy spectrum indicative of turbulence without a conventional inertial cascade.
