Helicity within the vortex filament model
R. Hänninen, N. Hietala, H. Salman
Kinetic helicity is one of the invariants of the Euler equations that is associated with the topology of vortex lines within the fluid. In superfluids, the vorticity is concentrate…
Energy and angular momentum balance in wall-bounded superfluid turbulence
J. J. Hosio, V. B. Eltsov, P. J. Heikkinen +3
A superfluid in the absence of the viscous normal component should be the best realization of an ideal inviscid Euler fluid. As expressed by d'Alembert's famous paradox, an ideal f…
Dynamical scaling of the critical velocity for the onset of turbulence in oscillatory superflows
R. Hänninen, W. Schoepe
The critical velocity v_c for the onset of turbulence in oscillatory flows of superfluid helium is known to depend on the oscillation frequency omega, namely v_c ~ sqrt(kappa*omega…
Quantum turbulence in propagating superfluid vortex front
V. B. Eltsov, A. I. Golov, R. de Graaf +4
We present experimental, numerical and theoretical studies of a vortex front propagating into a region of vortex-free flow of rotating superfluid 3He-B. We show that the nature of…
Twisted vortex state
V. B. Eltsov, A. P. Finne, R. Hanninen +4
We study a twisted vortex bundle where quantized vortices form helices circling around the axis of the bundle in a "force-free" configuration. Such a state is created by injecting…
Vortex Multiplication in Applied Flow: the Precursor to Superfluid Turbulence
A. P. Finne, V. B. Eltsov, G. Eska +5
The dynamics of quantized vortices in rotating He-B is investigated in the low density (single-vortex) regime as a function of temperature. An abrupt transition is observed at…
