Acoustic turbulence of second sound waves in superfluid helium
V. B. Efimov Institute of Solid State Physics, Russian Academy of Sciences, Chernogolovka, Moscow region
Abstract:
The anomalously strong amplitude dependence of the second sound wave velocity allows experimentally studying the behavior of nonlinear waves in a linearly dispersive medium, the processes of energy transformation from single-frequency harmonic pumping into the high-frequency dissipation edge of the spectrum, and the formation and decay dynamics of direct and inverse energy cascades.
Keywords:
superfluid helium, acoustic turbulence, turbulence, second sound, nonlinear waves.
