Evaporation of a packet of quantized vorticity
C. F. Barenghi, D. C. Samuels
A recent experiment has confirmed the existence of quantized turbulence in superfluid He3-B and suggested that turbulence is inhomogenous and spreads away from the region around th…
Polarization of superfluid turbulence
Carlo F. Barenghi, Sarah Hulton, David C. Samuels
We show that normal fluid eddies in turbulent helium II polarize the tangle of quantized vortex lines present in the flow, thus inducing superfluid vorticity patterns similar to th…
A Taylor-Couette Dynamo
Ashley P. Willis, Carlo F. Barenghi
Recent experiments have shown that it is possible to study a fundamental astrophysical process such as dynamo action in controlled laboratory conditions using simple MHD flows. In…
Magnetic instability in a sheared azimuthal flow
Ashley P. Willis, Carlo F. Barenghi
We study the magneto-rotational instability of an incompressible flow which rotates with angular velocity Omega(r)=a+b/r^2 where r is the radius and and b are constants. We fin…
Hydromagnetic Taylor--Couette flow: wavy modes
Ashley P. Willis, Carlo F. Barenghi
We investigate magnetic Taylor--Couette flow in the presence of an imposed axial magnetic field. First we calculate nonlinear steady axisymmetric solutions and determine how their…
Hydromagnetic Taylor--Couette flow: numerical formulation and comparison with experiment
Ashley P. Willis, Carlo F. Barenghi
Taylor--Couette flow in the presence of a magnetic field is a problem belonging to classical hydromagnetics and deserves to be more widely studied than it has been to date. In the…
Competition between rotation and turbulence in superfluid He
Tsunehiko Araki, Makoto Tsubota, Carlo F. Barenghi
Two types of vortex states have been much studied in superfluid He. The first is the vortex array in a rotating container. The second is the vortex tangle in turbulent flow. An…
Decay of superfluid turbulence via Kelvin wave radiation and vortex reconnections
M. Leadbeater, D. C. Samuels, C. F. Barenghi +1
The elementary processes involved in the decay of superfluid turbulence in the limit of low temperature are studied by numerical simulations of vortex ring collisions. We find that…
