Turbulent Superfluid Profiles and Vortex Density Waves in a Counterflow Channel

Research output: Contribution to journal › Article › peer-review

Abstract

In this paper we study the two-dimensional profiles of the superfluid component velocity and the quantized vortex-points density in a counterflow channel where the influence of the walls cannot be neglected. The numerical results obtained show the presence of vortex density waves in the channel, as shown in a recent paper by means of the one-fluid model.
