Popis: | Recent experiments have yielded the interesting result that superfluid turbulence is suppressed at the entrance of a flow channel. This effect cannot be explained by a direct application of the vortex tangle theory alone. The authors analyze a simple extension of this theory which shows how the vortex line density is naturally attenuated over an accommodation length {delta} at the channel entrance in good agreement with experiment. The accommodation length provides a new connection between a wide variety of superfluid turbulence properties, some of which have been experimentally less accessible. |
