The paper presents an extended review of our knowledge and understanding of turbulence
in a superfluid (4 He and 3 He-B), a system in which turbulent flow can be greatly influenced …

The term “quantum turbulence”(QT) unifies the wide class of phenomena where the chaotic
set of one dimensional quantized vortex filaments (vortex tangles) appear in quantum fluids …

ALTHOUGH the birth of the Universe is inaccessible to experimental study, aspects of
cosmological theories can nonetheless be explored in the laboratory. Tiny inhomogeneities …

We report on observations of turbulent behavior made without requiring the use of Taylor's
''frozen turbulence''hypothesis. Initially, a towed grid generates homogeneous turbulence of …

A new experiment has been performed to study the formation of topological defects
(quantized vortices) during rapid quenches of liquid 4 He through the superfluid transition …

We summarize recent experiments on thermal counterflow turbulence in superfluid 4 He,
emphasizing the observation of turbulence in the normal fluid and its effect on the decay …

The energy dissipation of quasiclassical homogeneous turbulence in superfluid He 4 (He II)
is controlled by an effective kinematic viscosity ν′, which relates the energy decay rate d …

Decay of He II counterflow turbulence generated by applying a heat pulse to the closed end
of a circular channel is investigated using second sound attenuation. Several orders of …

We report a comprehensive study of turbulent superfluid 4 He flow through a channel of
square cross section. We study for the first time two distinct flow configurations with the same …
