Applications of Gaussian model of the vortex tangle in the superfluid turbulent HeII
In spite of an appearance of some impressive recent results in understanding
of the superfluid turbulence in HeII they fail to evaluate many characteristics
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 properties of
vortex tangle. It is designed to calculate various averages taken over
stochastic vortex loop configurations. In this paper we use this model to
calculate some important characteristics of the vortex tangle. In particular we
evaluate the average superfluid mass current J induced by vortices and the
average energy E associated with the chaotic vortex filament.Comment: latex, 7 pages, 1 Postscript figure, uses subeqnar.sty, sprmindx.sty,
