An Introduction to the Theory of Superfluid Turbulenceimentally since the early 1950s that flow of the superfluid component of helium II can become turbulent when there is a steady counterflow of the two fluids, such as occurs in a steady heat current[.]. The original experimental discovery was accompanied by the beginnings of a theory[.], and this the

Numerical Methods for Coupled Normal-Fluid and Superfluid Flows in Helium IIinviscid superfluid in which vorticity is confined to quantised vortex filaments. These two fluids are coupled together by the mutual friction force. To model the normal-fluid flow we use the forced Navier-Stokes equation while the superfluid flow is modelled as motion of quantised vortex lines. In

Vortices and Stability in Superfluid Boundary Layers highlights a significant difference between the two fluid components that make up the current model of helium II: the difference in the boundary conditions. This two fluid model also has a fundamental effect on the stability of the flow, as one must consider the stability of both of the two fluid c

Grid Generated He II Turbulence in a Finite Channel—Theoretical Interpretationibed by a purely classical spectral model for homogeneous and isotropic turbulence. The He II vorticity is defined as ω = kL, where k is the circulation quantum and L represents the total length of the vortex line per unit volume, an experimental observable. The model accounts for the quantum effect

Vortex Tangle Dynamics Without Mutual Friction in Superfluid 4Hel friction did not work effectively [.]. It is unclear how the vortices decay. Motivated by this experimental work, we studied numerically the vortex dynamics without the mutual friction, thus finding some cascade process which was obscured by the normal fluid at higher temperatures.

Applications of the Gaussian Model of the Vortex Tangle in the Superfluid Turbulent He IIistics of vortex tangle needed for both applications and fundamental study. Early we reported the Gaussian model of the vortex tangle in superfluid turbulent HeII. That model is just trial distribution functional in space of vortex loop configurations constructed on the basis of well established pro

Applications of Superfluid Helium in Large-Scale Superconducting Systemsansient and steady-state heat transport, high Reynolds number flows, and two-phase phenomena. An effort is made to show the connection between the fundamental superfluid properties and the need of the application. Areas where further understanding of the superfluid state could benefit applications are also discussed.
