Developed Capillary Turbulence on the Surface of Normal and Superfluid 4He
The capillary turbulence on the surface of normal and superfluid liquid 4He has been studied experimentally. It is observed for the first time that the value of the high-frequency boundary ω b of the inertial interval increases significantly when liquid helium transits from normal to superfluid state, and that in superfluid He-II the correlation function of the surface deviation from equilibrium state in frequency representation can be described well by a power dependence with the index m close to −4.3.
