We present velocity spectra measured in three cryogenic liquid H 4 e steady flows: grid and
wake flows in a pressurized wind tunnel capable of achieving mean velocities up to 5 m/s at …

In 1970 and again in 1982, reviews were published which together covered progress in low-
temperature thermometry during the 1960s, 1970s, and up until early 1982. The intent of this …

The fluctuations of the vortex density in a turbulent quantum fluid are deduced from local
second-sound attenuation measurements. These measurements are performed with a …

The concept of''effective viscosity''$\nueff $ of superfluid helium, widely used to interpret
decaying turbulence, is tested in the steady-state case. We deduce $\nueff $ from …

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 …

The turbulence of superfluid helium is investigated numerically at finite temperature. Direct
numerical simulations are performed with a" truncated HVBK" model, which combines the …

Velocity measurements in turbulent superfluid helium between co-rotating propellers are
reported. The parameters are chosen such that the flow is fully turbulent, and its dissipative …

We report on studies of quantum turbulence with second sound in superfluid He 4 in which
the turbulence is generated by the flow of the superfluid component through a wide square …

An analytical model of open-cavity second sound resonators is presented and validated
against simulations and experiments in superfluid helium using a new resonator design that …

We report an experimental investigation of He II forced flow over a cylindrical obstacle by a
flow visualization technique that uses micron scale solid hydrogen particles. It was found in …
