A central question in the dynamics of vortex lines in superfluids is dissipation on approaching the zero temperature limit T→0. From both NMR measurements and vortex filament calculations, we find that vortex flow remains laminar up to large Reynolds numbers Re{α}∼10(3) in a cylinder filled with 3He-B. This is different from viscous fluids and superfluid 4He, where the corresponding responses are turbulent. In 3He-B, laminar vortex flow is possible in the bulk volume even in the presence of…

Vortex Formation and Annihilation in Rotating Superfluid 3He-B at Low Temperatures
In superfluid 3He-B the damping of vortex motion varies many orders of magnitude in the currently accessible temperature range from Tc to below 0.2 Tc. The large variation in the dynamics switches on
Thermal Detection of Turbulent and Laminar Dissipation in Vortex Front Motion
We report on direct measurements of the energy dissipated in the spin-up of the superfluid component of 3He-B. A vortex-free sample is prepared in a cylindrical container, where the normal component
Thermal Counterflow in a Periodic Channel with Solid Boundaries
We perform numerical simulations of finite temperature quantum turbulence produced through thermal counterflow in superfluid $$^{4}$$4He, using the vortex filament model. We investigate the effects
Mutual friction in superfluid He- B 3 in the low-temperature regime
We measure the response of a rotating sample of superfluid $^3$He-B to spin-down to rest in the zero-temperature limit. Deviations from perfect cylindrical symmetry in the flow environment cause the
Quantum turbulence in superfluids with wall-clamped normal component
In Fermi superfluids, such as superfluid 3He, the viscous normal component can be considered to be stationary with respect to the container. The normal component interacts with the superfluid
Energy and angular momentum balance in wall-bounded quantum turbulence at very low temperatures.
It is found that ideal behaviour is broken by quantum turbulence, which leads to substantial energy dissipation, as was also observed earlier, and the angular momentum exchange between the superfluid and its container approaches nearly ideal behaviour.
Vortex Core Contribution to Textural Energy in 3He–B Below 0.4Tc
Vortex lines affect the spatial order-parameter distribution in superfluid 3He–B owing to superflow circulating around vortex cores and due to the interaction of the order parameter in the core and
Andreev reflection, a tool to investigate vortex dynamics and quantum turbulence in 3He-B
The reflection process and results of numerical simulations of Andreev reflection from vortex rings and from quantum turbulence are described and spatial correlations of the fluctuating vortex signals measured by the different sensor wires are discussed.
Vortex filament method as a tool for computational visualization of quantum turbulence
The results are in agreement with previous studies showing that under certain conditions, vortices form coherent bundles, which allows for classical vortex stretching, giving quantum turbulence a classical nature.
Mutual-friction-driven turbulent statistics in the hydrodynamic regime of superfluid ^{3}He-B.
The present theoretical framework is applicable in quantifying the hydrodynamic regime of quantum turbulence and shows that superfluid ^{3}He-B in the presence of mutual damping exhibits a k^{-5/3} Kolmogorov energy spectrum in the entire inertial range.
